None of the parks are that close to my house, so I do have to drive to them so we only usually go after obedience class (the one with the creek is on the way home) and agility class is at another dog park/in a building that is joined to the park so Holly has a play before we start helping to get agility equipment out.
The parks are good though, but the jumps are too high for Holly so I don't make her jump over them and I haven't tried to get her to do the weave polls because I didn't want to screw up her agility training. But I have seen other people using them, especially if the dog park is empty. I think it's good that it encourages people to interact more with their dogs at the park
Holly goes through the tunnel sometimes and she likes standing on the dogwalk so that she's taller than the large dogs, especially if they start to get a bit rough for her (the dog walk is about human waist height).
But we have to pay dog registration to the city council every year so that pays for the dog parks and pound (I think a lot of the USA don't have to register their dogs, but I could be wrong)
