Tuna Man,
When I use the pontoon I try to arrange a turnaround with a vehicle that I can throw it in...my wifes minivan works when she is willing!
With the driftboat, I take all valuable gear out and leave the boat. Have used a bike and motorcycle for the turnaround, when I can't arrange a second vehicle. Have only had a problem with this twice...once some kids put the anchor in the boat and pushed it off into the river....came back at first light the next day with a raft to retrieve it. Another time some kids hid my canoe, but I found it. Best solution is a small sled until the water is too low and pontoons are the only way to float!
