Our dog is too. We've been to Mianus River Park and Montgomery Pinetum and most dogs we ran into were off-leash even though it's illegal. And most owners don't even bother recalling their dog. Very frustrating experience. At least Mianus was big enough to be pretty empty when we went except for the area near the parking lot. Montgomery I would not go to again, off-leash dogs around every corner.

We live in Waterside and John J Boccuzzi Park has a big grass area that's empty most of the time. However, if there are people with dogs, they will be off-leash so keep an eye out.
