Hutz - if you're looking for a nice 3-4 day hike, intermediate difficulty, check into the Cranberry Lake 50. Just like it sounds, it circles Cranberry Lake, but there are many other ponds/streams along the route as well as the Oswegatchie River. A small town on the SW shore (Wanakena) and a large campground on the NE shore, so you can break the trip up into whatever segment lengths you want. Also, many official ADK "lean to" shelters scattered throughout. It's up in the far NW part of the park, though, which means it's a haul to get there. The plus side is that it's less-visited.
