Heh, I know exactly what you mean. I got into one of those "cosmic rhythms" last monday while riding. It was pretty amazing, just totally spinning on my 48/16t fixie for half an hour without stopping or thinking or anything. I got so into it and zoned out that I ended up laying her down going into a turn at 27 mph. After a nice evening in the ER, I have a broken thumb/wrist and 15 stitches in my chin (it was burger down to the bone). Not to mention road rash all over and the new Cinnelli handlebar tape I put on LAST WEEK was trashed. So I'm out for 4-6 weeks till I get the cast off.

But yeah it was a pretty wild psychedelic experience up to that point. Just don't let yourself get too tripped out, you still represent a whole lot of kinetic energy whether your mind is there or not.
