The Neon Museum is a really amazing place. Founded in 1996, it is ever since dedicated to collecting, preserving, studying, and exhibiting iconic Las Vegas signs for educational, historic, arts, and cultural enrichment. The campus includes the quirky outdoor exhibition space known as the Neon Boneyard.
It has also lots of connections with The Killers as they shot part of their music video for All These Things That I've Done here.
