ive toked with my mom a few times (shes 64), my ex's uncle who was about 55, some older rasta people at bonnaroo, and some just plain old dude who i walked around with for a bit, not sure why
lol.
many other times that i cannot remember ive smoked with someone who is a little long in the tooth. older folks are very interesting people- they've got alot of years on me, and its cool to hear their crazy stories.
