Honestly, there was a playground that we went to occasionally, I swear the slide was about two storeys high. And it was just a great long ladder to climb, and a metal slide. I think I'd be terrified of it now!
Apparently, most of the evasive stuff the dog did to us, he does to his owners too, if he's in that mood. Basically, he won't let anyone leash him, until he's ready, and he will just back away leading you round in circles. It's just a waiting game.
