We've booked a preferred site, and since we'll be traveling with two dogs - I'm assuming they'll put us in loop 300. In looking at Shan-mans Google Earth, where do you access the pet walk? Is that it towards the back, near sites 331? If you were in site 320, (or that area) could you access it from the back of your campsite? What about the Dog Park? Is it only accessable from the sidewalk?
