Having watched this thread for some time, I wonder if there are others who use rolled up corrugated cardboard. It is certainly in plentiful supply and --when coiled to the proper density--it burns for long time. The duration of the burn can be increased is a handful of grass or weeds is placed on top of the cardboard. I learned this technique from the late Bill Steven. ************************* * Joseph Cooper * * [log in to unmask] * *************************
