From various 1960s-era nudist magazines:

HOLY CRAP -- Goodland Country Club and Lake Como Resort are still going at it! Shagbark Hollow Park, sadly, no longer lives up to its namesake (er, you know what I mean). Gymnos the Jaybird's home, Blue J Farm, has flown the coop as well. Sun Valley in Ontario doesn't exist anymore, but it lives on in the nudisploitation film Have Figure Will Travel.
