When Union County purchased the land for Hidden Valley Park, apparently there were some residents living there. Union County probably said, “Hey, we’re trying to build a park here, why don’t we buy your land from you, that’d be great” and the residents said, “WTF? Hell no!”
So there is a resident-shaped hole in Hidden Valley Park, with all kinds of “NO TRESPASSING” “PRIVATE PROPERTY” “NO FISHING” signs all over the place, presumably to dissuade curious hikers (like me) from skulking about and investigating this mysterious house on the lake.
EDIT, 8/31/12: I’ve just discovered— I think this is the Sayre Homestead, and it’s on the National Register of Historic Places!
