I have a BIG "back yard"!
Virtually all the wood I work with was "lost wood" from or near our home. Some came from roots unearthed during construction, some were wind fallen, others washed down stream during spring floods. There are a couple of trees too far up the mountain I'm waiting for my son to get big enough to haul out. One is a spalted birch about 2 feet in diameter the other is a very heavily burled birch! The splated one is laying across the trap line trail, it'll come out first, dang thing gets harder to climb over every year! I'll have to take a pic of the burled tree it is unbelievable how gnarled this thing is!
