Great dog park for space, shade, lack of soggy areas, and lack of ants. Only a small part of the park is lighted in the evening, so I think that's why a lot of unretrieved poop left behind - the place is big enough that you cannot see if/where your dog is going after dark. I tried after dark once, and have since limited my visits to the AM.
The incidence of aggressive dogs and dog fights is pretty low on weekend mornings (the only time I visit). Lot's of regulars are pretty good about talking to the occasional visitor with an aggressive dog. Abundant convenient parking, but don't leave anything valuable behind in your vehicle - I've seen numerous break-ins.
