PREVIEW CASSETTE # 212559 A Dan Fry home movie of a UFO believer s convention held at Giant Rock in California, early 1960s var shots Giant Rock (radio antenna perched atop it), adjacent rockface, granite runway, parked cars & trailers & small engine airplanes in crude lot, people congregating. MS man wearing shirt outfitted w/ designs of UFOs. MS man who may be George Van Tassel. MSs attendees. LSs men parachuting to events. Note: Giant Rock is the largest free-standing boulder in the world. Long considered an Indian holy site, the boulder s base was converted into a temperate, livable dwelling by Frank Critzer, a 20th cent. German immigrant and nascent miner. When Frank died under rather strained circumstances (locals regularly accused him of being a Nazi spy), former aircraft engineer George Van Tassel bought the property and turned it into a New Age-y UFO convention spot. Van Tassel is also the designer of the bizarre rejuvenation machine , the Integratron.
