Just picked up a load of Silver Maple, free from the city. They said take as much as you want, so I loaded up the pickup truck. Anyone burn this stuff? I've burned Sugar Maple, is it simular? I can't find a BTU rating on it. I'm figuring a medium hardwood. Doesn't seem as heavy as Sugar Maple or Oak. Also noticed the city has been cutting down some Oak trees to widen a road. I'm going to ask for some of that to.
