In another thread, a discussion started about what states people had traveled to (I am all but Alaska and Oklahoma).  But maybe a more appropriate topic for this group is in what states have you undertaken "self propelled water travel in some sort of craft".  I tried to make this a bit wide-ranging to include canoes, kayaks, and rafts (without motors).

Those traveling on waterways that form the border between multiple states get to count all the states they have been adjacent to (if you travel the Mississippi between Illinois and Missouri, you can count those two but can't add Louisiana unless you actually travel the river by that state).

My list: CA ID OR UT MT AR MO MN IL FL SC WV VA VT NH ME
