Your dog park is a lot bigger than mine and it has col tunnels and water.
My citys dog park is just a big fenced in area with another one on the other side for little dogs with a little water fountain for dogs and owners.
This is the best I can do this week.
(Ignore the clothes on the right, I tried cropping most of it out but if I cropped anymore out, I would crop some of Harley and *gasp* I couldnt do such a thing!! LOL)
