Okay, so this only about one film so far: The Beerdrinker's Guide to Fitness and Filmmaking a.k.a. Sullivan's Pavillion. I just picked it up today (29 September 2002) at a flea market. It is an incredible work of honesty and playfulness.
A nice essay on Beerdrinker's that originally appeared in Post Script 11.3 (1992): 47-53 Special recognition at the 1987 Sundance Festival A history of filmmaking in the Adirondaks, which mentions Fred G.'s films. Kirk Sullivan, Fred G.'s son, has a review here as well as a tentative offer for a copy of the film.
