Like oldnewguy, I also live in CT.
All respect to him but there's many places of historical value to visit in the northeast more interesting than the CT hills.
And while the Farmington River might be a blue ribbon tailwater, there's some excellent fishing in more scenic areas that might be better worth your time.
Cape Cod comes to mind as does the West Branch of Penobscot River in Maine in the Baxter State Park region.
You asked about smallmouth ? Try the lakes of "downeast" Maine (Washington county)
While in Maine you can't miss visiting the coast and if you have time, the coastal scenery is as good or better in Nova Scotia. There's Atlantic salmon fishing there too. (and you can see whales from shore)
There's 3 fly fishing museums in towns that were at the birth of American fly fishing in Roscoe NY in the Catskills, Rangeley ME, and especially the American Museum of Fly Fishing
in Manchester VT. The home of the Orvis flagship store.
All worth visiting.
