Hey Grouse,
sawbellies get up to about 7-8" in most of the lakes around west. + putnam. In the Hudson I've seen them to about 14". These are the "herring" you can buy during the spring run of stripers in the river. They're not the bluebacks that many fish for in Feb. + March in the salt. They can be caught the same way to be livelined though.
I fish for bass until the close of the season, and many times my biggest bass of the season come through the ice while I fish for panfish/trout/walleye. If the weather holds you could be using summer/spring tactics. Fish deeper once the eves start dropping to freezing.
Westchester has a lot of turkeys, but alas it's all privately owned. Make some friends and try seeking permission. Putnam has a few parcels of state land where there are turkey, but the pheasant/quail/rabbit hunters chase them out during the first week of Oct. If you bow hunt deer, you may get a shot later in the season when the woods quiet down. Across the river in Orange and Ulster there's a lot of good turkey terrain (Oak/beech ridges, farmland). Also in Dutchess and Columbia Co.s on this side. Good Luck, let us know about the bait.
P.S. sawbellies are very sensitive so bring a bucket with an aerator, throw in a handful of rock salt, and if it's warm a handful of ice. It will keep them alive longer. Also, use a white bucket, I'm not sure why, but it keeps them calmer. I use a black one occasionally and they beat themselves to death on the sides or jump out.
