There were usually ten to fifteen groups of people on the trails - judging by the cars in the parking lot. Dogs are supposed to be on leashes but we did not do so with Sandy. This couple had their dog on a leash. Sandy wanted to play with her and so did the dog, but the owners did not want them to do so, for some reason. I think it was because Sandy - half the size of the other dog - was sort of "beating it up," with the other dog submitting to Sandy. We ran into this couple at a lookout.
