I did the compost thing, now I have a big stinky pile of crud in the back yard. I tried spreading them in the flower gardens around the house all it did was attract mice. I'd dump them in the local hunting habbitat but the DNR would probably arrest me for illegal dumping. So from now on they get a ride to the county landfill in the big white garbage truck, of all the stuff I put in the garbage my spent grains are possibly the least offensive and acutually good for the dump.
