you could also check facebook and see if there is a group for your state?
I'm trimming the herd and have sold 3 machines on ours. Met all the buyers half way (they weren't terribly far away though.)
We also have a sister group for pony express too. If you have a machine in x town that needs to go to XYZ town you can put up a request, or if you yourself are traveling you can say I'm in X town, traveling to XYZ, anyone need a machine to go that direction. Really works cool.
