Trails may cross fields with cattle. You are expected to close the fence once you have passed. Do not enter fields unless they're clearly marked as part of the a trail. Cows, in particular when accompanied by calves, may act aggressively when disturbed. Pass cows quietly, without sudden moves or hard sounds, and keep at a distance of at least 20 m (65 ft). Do not position yourself between calves and their mother. Do not ever pet or feed cows. Dogs should be kept on the leash when cattle is around. It's even better to avoid cows altogether when walking your dog. If a cow licks your hand that's usually a friendly gesture. Still, it's best to avoid getting close to cows unless there's a fence between you and the cow;
