Brian,
I hope you didn't feel I was picking on you. Sorry if I gave that impression. This idea of hitting things comes up from time to time on the DB and it's something that concerns me in general. For example, I'm not sure I would call a metal door or a windshield a safe target! I'm glad you are past that.
Which reminds me of bands like the Who or the Clash - the way they smashed up instruments. I wonder what that was all about. Townshend used to smash a guitar to atoms before he had even paid for it!
Awhile back I had in mind to take a pipe wrench to the garden shed - just because it would be something I knew would be "unhealthy". Fortunately for the shed (and my hands) I got distracted.

Much love,
Larry
