After experiencing transportation hell in bringing all that stuff up the hill, we did manage to find a sled, and jerry rig something together to get stuff back down the hill. Granted the comforter did not really make it down in the same condition that it started, and it wasn't like it was a smooth ride all the way down, but we did manage to save a couple trips in the end.
The other fun part was that we were able to actually use the sled (granted it was for a 8 year old) on the way back up - I'll have to get those pictures.
