If you've been in downtown Boise and admired the old buildings, many thoughts have gone through your mind. You've wondered what that building was initially used for, or has this always been a bar? You've asked what it looked like when it was new before it had a giant neon sign attached to it. You no longer have to wonder.

An excellent website called "What Was There" combines Google Maps with vintage pictures that are user-submitted. They overlay those pictures onto Google Maps to let you see what places in Boise looked like then and now. I've included some of my favorite images from What Was There of Boise.
