I've got a purdy' long list.......but I'll keep it short.
I was finishing up the siding on one of the peaks of the house. I got to the top (15ft. or so) to nail another pc. when the catch on the extension ladder slipped and the ladder de-extended. I slid to the ground in slow motion one rung at a time. I must say that's a little hard on knees & ankles.
