I visited Jaycee Dog Park recently -- never again.
It's a tiny park, not much bigger than the backyards in the area. It was very nicely shaded, with a building on the west side, and many trees. Staying out of the sun here is not a problem, nor is finding a seat on one of its many benches. It also has a double gate, and plenty of parking close to the entrance. The city also supplies poop bags...
...but apparently no one has ever used one. When I had five dogs, my backyard didn't accumulate this much poop in a month. It's disgusting, and a health hazard. Who are the people who don't clean up after their dogs?
Other issues: The grass is excessively long in the areas where it grows. It looks like a weed garden in some sections. The ground is covered with trash, mainly of the bottles/cigarettes kind, along with candy wrappers.
Beware, small dog owners. There is a gap large enough for a 15-20 lb. dog to pass between the gate and the fence on each of the two gates in the entrance. It would not be difficult for them to escape to the main park.
