Thanks, all! I don't really have claustrophobia, and in fact if there's something opposite, I probably have that. I actually like crawling into tight areas; I sometimes think I should have taken up spelunking.

In fact, when I sleep I often have this bad habit of wedging my body in the little space between my bed and the wall. It sort of makes me feel "safe". Yep, wierd.

I didn't know they were loud, but I think I'm OK there, too. I'm used to shooting (I know you are, too, Mark). I take it you can't use your own shooting ear muffs?
