Are there any duck ponds to take the kids and feed the ducks in or around Wappingers Falls?

The only place I can think of which comes close to fitting this bill is Reese Park, not far off of Route 9D, which is just outside the main village of Wappingers Falls. It's located along the banks of the Wappinger Creek, featuring a pond. Its website boasts a duck habitat, amongst other wildlife, and there isn't anything that says you can't feed the ducks there. I would think this is your best bet.
