When I lived closer, I used to visit this park pretty regularly. The people are friendly, and the dogs tend to be mellow. As the other reviews have stated, there is no separation for little and bigger dogs, so if your pup is aggressive or overly timid, this may not be the right place for you.
There are a few covered benches, and they keep the place clean and the grass nice and watered. Also it is well lit after dark. The park technically closes at 10:00, but they don't really lock it up, and I've been there at midnight a few times without being hassled.
It is a nice sized space to be able to sit and keep an eye on your pooch at play. Not so small that everyone is cramped, but not so large that you loose sight or have to go chasing all over the place trying to get the dogs reigned in.
All in all, a really nice park.
