Muskrat
Muskrats are common across the state. While considerably bigger than plain old rats, they are nowhere near the size of beavers, which can get to 50 pounds. Muskrats have tails that are slightly flattened from side to side, unlike beavers which have broad flat tails. Both animals build conical houses in the water, but only beavers build dams.

Harbor Seal
Harbor seals are not uncommon in the winter, but kayaking is, so don't expect to encounter them when you are out for a paddle.

This is a scupper cart. It is a set of wheels that fits in the scupper holes of the kayak and lets one person wheel it around like a wagon. The big advantage of this sort of cart is that when you get to the water, you can pull it out, flip it over, and stick it in the top of the kayak. Then off you go - no need to double back to put the cart away. Also, you'll have it if you get somewhere that you might want to portage.
