As long as the wind is good enough for me to spend most of the day on the wire, my back is ok now. But if I have to spend the whole day sitting on the tramp, bent 90 degrees at the waist and slouching, it will hurt pretty badly after a few hours and be very stiff that night. I can trap all day with little pain afterwards, if I keep my back straight. Of course it is a good excuse when the wife wants me to take out the trash! <img src="http://www.catsailor.com/forums/images/graemlins/blush.gif" alt="" />
