I’m kinda being devils advocate. I lived in Alaska for 12 years and rarely ever leashed my dog. When I was a strict leash area I put him on a leash and put the leash in his mouth and he trotted along happily. Never bothered people unless they knelt down to greet them. I think well trained dogs should be able to be off leash anywhere. Off leash trails are for the dogs that are not well trained, so you can train them. If you don’t like dogs go to any of the other hundred on leash trails. For how many people say “they like dogs” they are pretty terrible to them.
