To legally access PoohBah from anywhere in US, you must clear Canadian customs, and have a valid entry permit. If you use a tow from Crane Lake, they will stop at Sandpoint L (customs), and Native villiage (permit & fishing liscence).

To paddle up from Moose River bypasses both, and if caught, you could forfeit your whole outfit. I would not take that risk. It would cost a whole lot more than the tow.
