Tripping adds extra layers to an experience. If you can handle being in that special state while doing something intense, it can be a beautiful, memorable, whatever, experience. It's not for everyone, I think experienced people kind of know what they are comfortable doing while tripping. I recently found out a friend of mine skied one of the biggest, most committing lines in our mountain range with a head full of mushrooms. I was very impressed with the nerve and boldness that must have taken. I would have never dreamed of doing that while tripping, but hey, to each their own.
