I saw this movie when it first came out - 1969.  I thought it was vapid/self absorbed and just plain dopey.  2 losers set out on their idiotic Capt. America harleys - after their drug deal-  on a half witted soul search.  There's a scene with a "commune"- a commune of bunch of nit wits.  Stinks.  The sound track is good and that's about it.  By the way as you watch the idealistic commune life- remember about 2 months after the release of this movie there was another famous hippie commune in 1969 - led by Charles Manson.
