New Wheelchair for Rob

We went to the dump with the wheelchair tied on top. Sue took the chair down and unloaded the truck. We drove off and no less than 5 minutes, we turned around and saw "chairy" was not there. Did a U turn and when we got to the dump, the wheelchair was gone. I am so upset about this. I couldn't get out of the truck because I didn't have a spare chair. We got a very heavy loaner while we wait for the new chair. This is just plain lousy. If you can help, thank you. If you can't thinks for looking. May have the chair by early next week.
