Dog waste piling up at Wyoming forest trails

A smelly problem is piling at trails around Jackson where people go hiking and cross-country skiing with their dogs. How big is this problem? Bridger-Teton National Forest officials say they recently counted 173 piles of dog waste around just one trailhead.
The problem is so bad, it's contributing to elevated bacteria levels in nearby streams.
District Ranger Dale Deiter said the situation is "not acceptable." He's promising to step up enforcement so people clean up their dogs' acts.
