The National League of Cities held its 2015 Congress of Cities and Exposition in Nashville, Tenn. The largest gathering of local elected officials in the country, the Congress of Cities was held at Nashville’s new Music City Center. Pictured above is one of the many talented local musicians who entertained guests throughout the week on a stage sponsored by the City of Nashville.

Opened to the public in May 2013, Music City Center provided an unmatchable location for NLC to hold its annual national conference. The Congress of Cities gave city leaders the opportunity build technical and leadership skills through educational seminars, attend mobile workshops around Nashville, and participate in workshop sessions spanning the topics most relevant to their communities.

Music City Center also provided an elegant and inspiring environment for city leaders to meet and build relationships with other local leaders. Seen here is a four-story mobile sculpture, titled Euphony, by artists Benjamin Ball and Gaston Nogues. Depending on the viewer's vantage point, the 1,141 multi-colored stainless steel chains blur to a vapor-like visual composition or appear as a hard-edged geometric form.

The Congress of Cities featured an Exposition Hall where more than 275 vendors were on hand to introduce city leaders to new products, services, and programs that could benefit their communities. The Exposition Hall also featured an NLC Pavilion showcasing our sponsors and corporate partners as well as an “Innovation Central” area where startups could share innovative ideas.

Our business partners also had the opportunity to host “Solution Sessions” at the conference. These sessions presented a unique education and marketing opportunity for organizations to demonstrate thought leadership and provide industry analysis important to city officials, deliver case studies and best practices, or create dialogue and the exchange of ideas on a topic important to elected officials.

For many delegates, the Congress of Cities began on Wednesday, Nov. 4 with a number of mobile workshops. The City of Nashville offered off-site workshops to showcase collaborative solutions to issues facing local government. Seen above, conference delegates explore the newly rebuilt Nashville riverfront, which features miles of off-street multi-use greenway trails, an amphitheater, a dog park, playgrounds, and stations for the city’s bikeshare system that include innovative bicycle repair stations for public use.

NLC recently launched the Cities Lead 2016 campaign to make city issues a focus in the 2016 presidential election. NLC has asked presidential candidates to focus on the three issues highlighted as most important to city leaders in this year's State of the Cities study: the economy, investment in infrastructure, and public safety.

They were the founding members of NLC and they continue to play an important role at NLC, guiding the organization's priorities and serving as an important link to cities in their state.

NLC University offered a number of educational training seminars for city leaders throughout the conference.

Youth delegates and young elected officials gathered at the conference to talk about the next generation of leadership. This year’s youth delegation enjoyed a number of exciting events, including a mock Iowa presidential caucus, a social media-based scavenger hunt around Nashville, and an opening session keynoted by Chess for Humanity founder Akshay Malhotra.

Youth delegates participate in the mock Iowa presidential caucus. As delegate Melanie Navin noted on our Facebook page, “[The 2015 Congress of Cities] was absolutely amazing. I appreciate this event so much and highly recommend it to other Youth Councils, because you WILL learn, you WILL get ideas, and you WILL want to make a change in your community.”

The National League of Cities was honored to have Vice President Joe Biden deliver the keynote address to city leaders during the 2015 Congress of Cities. “I have never been more optimistic about the possibilities for this nation than I am today,” stated Vice President Biden. Addressing city leaders, he said, “There is so much we can do – but we need you.”

During his speech, the vice president looked back on his time as a county council member in Delaware and thanked the local officials present for helping to make the Obama administration's economic recovery initiatives successful in pulling the nation out of a recession. Biden also said a big need facing the nation as it continues to make economic recovery is "a resurgence" in education. He called for free community college, which he said could be funded by cutting tax deductions.

The vice president drew laughs when he stated that “Local government is too damn hard, and the people know where you live,” adding that, "If I never go to another zoning hearing, I will die a happy man.” Displaying his trademark affability and warmth, the vice president made time to work the rope line following his speech. Here, he pauses for a photo with New Bedford City Councilor Steven Martins.

Musician Darius Rucker of the band Hootie & the Blowfish and Nashville Mayor Megan Barry joined the CMA Foundation to announce a gift of $1 million to the Nashville Public Education Foundation for music education. Addressing the crowd, Mayor Barry noted, “Music makes engaged students, who make engaged citizens.”

NLC leaders weren’t the only conference attendees who found a moment to kick back and have a good time during the Congress of Cities. We’re not sure where these delegates found their feather boas, but we’re strongly considering adding them to the registrants’ gift packages next year.

NLC staff worked hard for months to make the 2015 Congress of Cities happen. Our goal was to deliver an exciting, engaging and memorable conference for the city leaders and local elected officials who made the trip to Nashville this year. We hope you’ll let us know how we did, and we look forward to serving you again next year.

Next year, the Congress of Cities will become the City Summit. If you haven’t been to Pittsburgh in a while, get ready to be amazed when you arrive in a lush and lively city with top-notch museums and universities, miles of riverfront trails, and more than 90 bustling neighborhoods. How did the city of Pittsburgh transform itself? Come to City Summit 2016 to find out! We look forward to seeing you next year.
