Have traveled the Cabot Trail a number of times. Back in 2004 I came upon a number of people feeding a coyote by the side of the road. They were tearing pieces of a sandwich and throwing it at the coyote. One of the guys was a moose hunting guide. Coyote would come out to retrieve the food and head back into the trees and foliage. I took some photos and didn't think much about it. Next day went back hoping to see the coyote again and hike the trail as well.
Park Warden's truck parked by side of road and trail where people fed coyote day before was now closed. Apparently, a coyote was reported stalking some hikers earlier in the morning. Likely same one that had been fed. Park warden explained the coyote had circled their truck and they had to shoot at it. The coyote yelped and disappeared into the woods. It was never found again. The warden hoped the coyote would now be "gun shy" and not return. Coyotes that show aggressive behaviour are not relocated but killed instead.
I wondered if the aggressive behaviour was due to rabies but the warden explained that if it were rabies, you would hear about it from hikers because it wouldn't be limited to just one animal. There would normally be more than one animal affected and the reports would come in. I heard that there were other such incidents although they are rare.
The Skyline Trail where the 19 year old girl (story linked above) was killed offers a beautiful vista of the Cabot Trail. The trail is also known as a great place for seeing moose. I saw a number of moose up close while hiking the trail. Hope to go back soon but you can be sure I'll never walk it the same. Carrying a monopod at minimum and a canister of bear spray.
