yet, I have seen the author of this article walking the crevasse Moraine trails with multiple dogs... all unleashed and out of control, out of sight and not responding to her repeated calls.. She advised they needed a place to run and "chase rabbits and squirrels"! While trapping is legal, purposely allowing your dog pack to chase wildlife isn't. As a Wildlife Trooper I lived adjacent to those trail systems and used them as often as anyone. Retired now, my partner and I probably use them more than any others.  Dog related problems are the only problems I have observed or heard of on the system, including last year when gun fire was used by a family farm to stop a charging dog. I've been knocked down by a womans dog, there is now posted a sign advising dog owners not to pick up their dogs poop.  I'll take trappers any time. My dog is under control and I have no worries about traps.
