my best acid trip ever was about nine years ago. after eight days of climbing my bro larry and i had just topped out on a route on the big stone called space. my friend had to get back to potland, he suggested that we take a quarter hit of some acid that he claimed was old and not very potent so we could get up some energy and bust out the east ledges that night. well five minutes later i was zingin hard. we carried are flying pigs down to the top of ZM so we could toss our bags. i could barely walk i was trippin so hard. we ended up spending the night on top with a full moon and the southeast face of el cap as our veiw. it was a long night and we had some interesting conversations with other climbers who had topped out that evening. that was the best two dollar vacation i have ever had.
