I was, like, I know I've heard that somewhere before. So I asked Secret Agent Google and she told me. So that doesn't count and I'll leave it open for some true child of the 60's to answer. I did get the "cowboy Neal" reference though.
That place you posted pictures of sure does have the Cadillac Ranch beat hands down!
I got serendipitied into a crawl-all-over-it-tour of the 2nd Further! bus one night. Supposedly the 2nd one was the one that went to Woodstock and turned on the Beatles and Tom Wolfe, etc. It was being campaigned around the country trying to raise money for a Ken Kesey Museum and Conference Center on his farm. The guy telling me the story claimed to be his son. I'll post my pics of it up here in an album sometime.
Ken Kesey's son is charlatan and ALWAYS looking for money. NOTHING like his father!!!!!!
