I beleive I did in 1976. We all Decided to Celebrate our Country's Bicentenial Birthday. The plan was for all of us. Apprx. 6 people To attempt to pull 200 one hit bongs, of some good Gold Bud that was around at the time. I know for sure that we didnt make it to 200. but I dont even remember how I got home that night. I was only smoking, nothing else. so I would say I blacked out that evening. That's an OD to me I suppose.:thumbsup:
