Our local lumberyard is always giving away pallets, some of which I've stacked wood off the ground on. Today I cut up some newer pallets into enough kindling to nearly fill a garbage can with 8 inch long splits. I assume they make pallets out of junk wood no good for anything else because it's full of knots sometimes making it difficult to split. The wood feels pretty light possibly even cotton wood. Oh well, should make good starter kindling with about 30 seconds of propane torch action during cold starts. Anyone else use pallets? I'd advice against using anything that is treated. I doubt they spent any money/time on kiln drying it either.
