This is only the second dog park I've ever taken my dog to (the other was Cosmo Dog Park in Gilbert) and I liked it much better. I took the risk of going at noon on a Saturday afternoon and was pleasantly surprised. There were about 20 dogs in the park, but because the area is so big, it didn't seem too crowded. The dog has very little "dog mess" around, which shows me that people take pride in the park and generally clean up after their dogs.
My only complaint is that I saw so many owners with food, which has a tendancy to cause issues with some dogs. Owners were giving dog treats to dogs (a big no no) and there were a couple young kids walking around with ice cream bars with dogs following them (just asking for a dog to knock over your kid to get the yummy treat). All in all, I'm a big fan. I guess you'll see stupid people at every dog park, right?
