Any Hikes in VT and NH Along a River?

If smaller brookies are OK, the AT in southern VT. has lots of opportunities along creeks, some bigger fish in ponds and following the streams to main branches. I use a 1 wt. fly rod.  I use a float tube with a 3 wt.  in the ponds and do VERY well.  I'd also think about an upper Connecticut Lakes canoe trip. 
You might think about pack rafts. They'll limit the miles, but your kids will have a blast with the on the ponds. They're great to spin fish out of, not so much the fly rod.
