Enough of these drug accusations.
Has anyone ever seen dad do drugs??
Pot ...maybe.
Alcohol yes.
LSD etc...no.... because it was rare as hell. I have only heard of or seen him take lSD in tiny unnoticeable doses 2-3 times over the last 30 yrs of his life.
He and others did it largely back when it was legal. Then they grew up. 
But...the media likes it's sound bites. ...he NEVER drove a bus cross country handing out LSD... that is false!
