If you can't find someone to drive your boat, I have used amtrack to ship rafts and other things. You have to call for rates. It use to be really cheap, Like $45 for the first 100 pounds and $0.20 for additional pounds. It has to fit on a pallet, which a raft does. Denver to SLC are on the same route so it's pretty simple, if John or someone at IT will drop it off at Union station in Denver. Then you pick it up at the station in SLC.
