I demolished old house this week, built in 1900, out in the country, been used as a haybarn the last 40 years. It didnt have any indoor plumbing or wiring, just old thick ass lumber and a tin roof, no insulation. The last tenants had tacked strips of cardboard over the gaps between boards, trying to stay warm I guess. It was kinda sad, but if I didnt take job, somebody else would anyway, so I just handled it reverently. I dug a really deep, wide hole right beside it, caved roof in with excavator, put lil in hole, got it started, and when heat wasnt running me off, kept chunking it in. That sumbitch did get some kinda hot, but got it all down and burnt in one day and covered hole up next day. All reverently, mind you,,,,,randyp
