Great idea, I pulled a dog sled with my snowmobile and kept a throwing ring and rope near the back of the sled where someone could stand, never had to use it but it was there. I pull a 2 man clam now, sold the boat and the life ring went with it, I'll have to get something else. Those throwing bags look interesting, but using the tow rope from a smitty or a flipover would work also, alot easier to get to. thanks
