On the pro side: Burning all but the most toxic waste, during all but the driest drought weather, is legal (in Virginia) if you burn in a nice solid metal barrel. Leaves, wood, garbage, junkmail...and what you scooped out of the litter box converts from "nauseous" to "Hey, where's the barbecue?" (Worked on my neighbors, anyway.) On the con side: That's because it is hard to get a fire going in a barrel. Fire burns up, but just try to get a match down to the tinder, or add more tinder if the first layer has not ignited the kindling. Thoughts? Experiences?
