Another strong recommendation for this unique place. I visited soon after its 1988 opening. The museum was so off the grid and unknown that early visitors like me received personal guided tours of unlimited duration from its founder/creator, David Hildebrand Wilson.
I am green with envy, that sounds amazing.
Do you remember any exhibits from that time that aren't in place today?
It was wonderful. Scintillating. Alas, that was in the late 1980s and I haven't been back, though from the photo in Wikipedia its kind of derelict/dumpy entrance looks like it hasn't changed at all.
If you read "Mr. Wilson's Cabinet of Wonder: Pronged Ants, Horned Humans, Mice on Toast, and Other Marvels of Jurassic Technology," Lawrence Weschler's superb 1995 book about the museum with extended interviews with Wilson, you will find it hard not to want to visit.
