Sure is - - - - - http://www.ohtm.org I was at an aviation function there last Saturday. A group of EAA chapters were invited guests(admission FREE).
After the presentations we had free reign to tour the whole facility, with a guided tour of the big hangar where all the maintenance and restorations are done. I've been there more often since I moved away from Cushing(over which you regularly fly) that when I was growing up and going to high school in Rockland.
