My father and I visited the American Sign Museum in August 2012. We skipped the group tour and walked around by ourselves and enjoyed looking at the great collections and reading about the different materials used to make signs during different eras. It is a wonderful place for photogaphy as there are several opportunities to snap shots of items that are often no longer in circulation.
We parked on the street before we realized after walking around the back of the building that there is an actual parking lot.
Good place to visit, clean, interesting, and a lot of neat history here! Plan to spend 1-2 hours browsing.
