October is a good time to catch big brown trout moving up rivers to spawn, so exploring some streams with good wild populations of brown trout is a good option.
Here are a few others:
Striped Bass with possible shots at False Albacore- Martha’s Vineyard or Cape Cod MA, or Montauk, NY
Landlocked Salmon on Lake Champlain tribs, NY
Salmon Fishing on Lake Champlain Tributaries - NYS Dept. of Environmental Conservation
Steelhead and big lake run brown trout on great lakes tributaries to Lake Ontario in NY, and/or Lake Erie in PA
