New Englanders?

got a denali lama this summer, two actually (hoping my wife would join me),havent shut up about the thing, been putting it in every river or body of water I can, have no idea where to actually get the inteded use out of the thing. (backpacking, camping, river running and back packing and camping all over again.) Any ideas? Im looking for ideas for a trip in greater New england of 4 days or more using the packraft. Any New Englaners with a little more experience willing to show a novice the ropes, even if only for the day, or that run some rivers other than the Saco? I would love any ideas.
