I visited my sister in Fort Collins, CO, last summer, and was so excited to go back for a couple days during our trip! FC has the cutest downtown area (locals will call it "Old Town") that's chock full of restaurants, bars, & shops--I don't think I saw a single empty storefront. There's also some great sculptures & public art, like this bear friend.
Fort Collins has this cool ongoing public piano project--local artists paint pianos under a little outside tent in Old Town and the pianos are placed around the city (or at least, in the area). Anyone can play them, and lots of people do! It's so cute to see kids pounding out "Frere Jaques" or laughing adults struggling through "Heart & Soul". Dane decided to play a little tune for me :)
