That's just what I was thinking about, Bill. For one thing, I don't "hurry" anywhere, anytime. And 20-30 feet is a long way, especially when you've about reached your saturation point.

I've bundled up and tromped over to the Post Office when it was 30 below zero. Almost no matter how cold it is, I can pile on enough wool and down and polartec to keep warm. There is, however, a limit to how much you can peel OFF in polite company.
