My puppy Rose and I had a great time there today! I've been leery of dog parks in the past, but this is a great place. It is large and very clean. Rosie and I met some really nice people and dogs there today. We both got some exercise (well, only one of us is asleep right now). We'll definitely be back!
Doggie bags are available near the entrance. Trash cans are set up around the park. The only thing I wish they had was doggie water fountains. Yes, I know it's winter; I'm just saying.
Also, the county park has lots of different sections/parking lots/entrances. As you get close they have helpful signs pointing you towards the dog exercise area. Rose and I can't wait to go back!
