I happened across these last night and saved them to my flickr account but now I can't find the original website. Today I find that Mountain Man has posted some art and demolition derby photos from his own visit to a Pennsylvania fair!
UPDATE - still can't find the original site but it may be on one of the many bizarre pages of this website of photos by the photographer, Craig S. Thom. Am I allowed to post that butterheads photo? I don't understand the rules.
