Playing guitar, obviously. Occasionally there comes that transcendant time when you're playing on your own, and you know it's all perfect. Best though is playing with others, when you're getting really tight as a band, and you know it's good bcos you can see the smiles on the other guys' faces.

Hang-gliding and skiing as well. Skiing is nice, but hang-gliding is better - take the feeling of a wonderful clean fast schuss, multiply by some, and that's hang-gliding. Approximately 1 part scared to 4 parts excited!

Also walking. I love anywhere without light pollution, where you can feel in touch with the land around you. The ultimate expression of that was age 18 when I walked the West Highland Way. There's a long section over Rannoch Moor which I did in a day - it had rained every day up to then, but that day was clear and stayed good, so I decided to push on. At the end of the moor the path goes up over a ridge and down into the Kingshouse Valley beyond. I reached the top of the ridge at the end of the day, just when the sun was starting to go down and the heather was shining. I don't know how long I stood looking down the valley, and I couldn't begin to describe the view, because words couldn't match it. The only suitable word would be "holy" - no church or cathedral or preacher has ever come close to inspiring that feeling.
