FISHING
There are a few places to go, off the top of my head the CT River jumps out as the closest. Warwick has a couple of nice small lakes (30 acres or so in size). Plenty of streams to fish and one reservoir up the mountain from my house that's "off limits" but that never stopped us before.
Common fish - Bass, Trout, Pike, Pickerel, Muskie, Carp, eels, and a half dozen others..... Bring your favorite spoons, and floaters can't go wrong with them... I haven't fhished in MA in years so I can't tell you how good it is or has been...

LICENSING
Age 15 and over you need a license to fish. A 3-day "non-resident" license runs about $25.00. You can get one online at the link below or you can get one at the town hall in Northfield.
