In reply to Ferrito: I went to see him at the Hen + Chicken in Bristol a short while ago. He splits his talk into segments, covering deep-water soloing, base jumping and wing-suit parachuting; each is illustrated with short films, photos and a great many anecdotes. Tim has a distinctive and unusual blend of wit and engaging enthusiasm; when he starts talking about these sports his eyes light up like 100 watt bulbs. It's hard not to warm to the guy, though you have to give yourself an occasional reality check, as you realise he's just described climbing a huge wall to an otherwise inaccessable ledge, throwing all his climbing gear and ropes off the edge and waiting for a gap in the clouds to parachute through as though it is the most normal thing for anyone to be doing of an afternoon.
It made for an energising experience and I would recommend him, not just to climbers, but to anyone who enjoys a good evening out.
