Kayak in Portage Mode

Kayak in Portage Mode
I'm getting ready to pull the kayak down to the launch ramp (there's no good place to put it in at the marina) and go out on the St Jo river for a few hours. The wheels are small and make it hard to pull, but it's managable and it all comes apart so you can take it with you easily.I really need to get a cooler or box that fits in the well behind the seat.
