Once 20 years ago my brother stumbled across some 7ft plants next to a trail we used to ride our dirtbikes on. It was right there, not even hidden. We rode past it many times. Looked like it had been there several generations. That was hands down by far the highest I have ever been. I was walking down a hill, but I was so hypnotized I didn't know it and started freaking out because I suddenly realized I could not stop walking! My brother says "youre on a hill, dill rod" or something like that and WHAM! The world shifted and I was indeed on a hill! It was like tripping. clean, pure, massive world-shifting high. I remember some purple in it, thought that was odd, thats all. I have been trying to find something like that again, never even close. It's like that blonde in the Thunderbird in American Graffitti -- I flew off and never seen her again. Dang! So, I would ironically have to say that my favorite was some nondescript ditch weed we found! LOL
