dh took me to the adams (john & john quincy) homestead for my birthday last august... @ the last house (name escapes me at the moment) there is a separate outbuilding which was the first presidential type library...
while we were in there (on a tour with park rangers) i was kneeling on the floor... the mosaic was an ohio star pattern...
the ranger told me i was the 3rd woman to tell him that...
