Mike,
There is a fellow East of Brainerd about
1 1/2 hours at Palisade, MN that does a good job of selling wood. Have sent a number of people to him and they have been happy. Web site is as follows:

also know of an Amish saw mill about 10 miles West of Staples on Highway 210 he is open the year around and has lots of green basswood on hand. I have bought some from him and it is good.
