the blue quasar: gt.us: Just about everything I've seen in the Smithsonian Inventory of outdoor art could be waymarked in another category. I can't remember what I saw that I couldn't think up a category for.
Something as significant as the Smithsonian should have its own category IMHO.

It should, but I don't think this is it. The art in this database doesn't necessarily have anything to do with the Smithsonian, and it's way too big, IMO. The Detroit Institute of Arts alone has over 1100 entries. That would be a lot of waymarks within 0 mi of each other.
