I don't know if anyone noticed the actor in this who later became the character "Grizzly Adams" in this movie. He has played several bit parts in these biker "B" movies, including a scene in "Easy Rider", you can find him in the "commune" part where the camera pans around during a prayer before they eat. I don't remember some of the other movies, but, if you look for him, he turns up like a bad penny in several. Bottom line is, you have a bunch of lame kids-of-famous actors playing in SoCal with cameras cranking out crap, getting stoned and being in each other's movies.
I paid the price for movies like these in the late seventies as a Harley riding biker, people actually believed some of the crap Hollywood cranked out from this period, now, it's more believable, like say "Wild Hogs." (right)
