Logs To Lumber - If you do any serious amature woodworking you need to talk to Brian! This guy was not pleased with the quality of ANY mills in the midwest so he bought his own mill. He has the best prices and quality of any lumber you will find anywhere in the twin cities. Plus his stories are increadible. Plan on at least 3 hours of chatting if you go there.
