Look in your phone book and on the web to find someone with a portable log milling machine. Call them and they might want it. The log might be beyond saving already.

Put a free ad in your local CraigsList in the 'materials' for sale section. We get lots of fallen tree ads in there, and I think local woodworkers haunt it regularly.

Or just the "free" listings on craigslist, it gets a lot more traffic than the "materials."
