Man I don't know there were quite a few. My first time on shrooms was pretty special. Did them on my own and spent about hour an a half on my back in a field staring at the sky seeing amazing patterns. Then I saw a light flashing on the river and I half believed it was this big mushroom calling me so I went to investigate it. Had to crawl through hedges to get there and when I got there it turned out to be a night fisherman. Talked to him for half an hour absolutely off my face and then went home ha ha.
To be honest I think being in your twenties is more fun than being in your teens.
