Dude, I can't be anywhere near a computer whilst tripping. I have to be out and about, I've gotta be doing something. I can't stand tripping and just sitting around the house.
You're right about the computer - when I'm tripping I feel so retarded staring at the screen and not even being able to open the one program I'd like to open...
But usually I try to take such high doses that I really need to lie down for at least half of the trip, and in the second half I need a very reassuring environment. The four walls of my home really serve me well with that reassurement.
I know tripping in nature can be great, but I haven't found a nice and reassuring place in nature in the last few years (absolutely no strangers there, and so on...).
I have done a few trips out in the fields and in the woods when I was younger, on medium doses of shrooms and lsd, and they always were great, no doubt about that.
