In reply to The Lemming:
I gave up winter climbing a few years back after a lucky walk away from a monster fall. The decision was easy; Id had a bad run and was fed up with walking for three hours to go ice climbing in the pouring rain. I soloed one more route, the next year just to get back on the horse, and walked away...
Rock is different, My soloing grade has slowly risen with age/number of children. Not through boldness, just getting better at staying calm.
Don't like to gamble though; getting buried alive in the Alps/frozen in a storm has never appealed...
