If you have a chainsaw, check out this ad for free wild cherry in St. Louis:
I just called Scott from the posting, and he said there is a bunch left. About 12" diameter, and ranging from 4' to 12' sections. It's free, just call him and go grab it.
If I had a chainsaw, I'd be all over this... but since I don't, I'll have to impose a small finder's fee in the form of fresh-cut cherry wood j/k
