Bears in the NorthEast
I have been backpacking for a number of years and I have had a few "interesting" experiences with the black bears that we have here in the NE. From my experiences, if you camp in a highly popular campsite, say Marcy Dam or Lake Colden Leantos in the 'Daks, you can expect to have bears nosing around. Good news is that black bears are territorial. If you remove yourself from the vicinity of an area known for bear problems to an ajoining area, where the resident bear is not used to human contact, then you can camp peacefully. On one trip to the Adirondacks, I returned from a day of hiking to find fresh bear marks on the tree in which I had hung my food. I immediately packed up and moved about a 1/4 of a mile away and camped at large, my food was unmolested. Another time at the Livingston Pond leanto, a bear was nosing around our tent, but luckily ran off when I woke up to find its head in the tents door and screamed. However, it did eat all the food of the unfortunate group camped in the leanto. I guess they weren't good screamers.
While these anedotes might make a good story for the kiddies, there have been black bear attacks. Most have not been fatal.
Example: Last fall, a hiker in NJ was stalked and attacked by a black bear. It was driven off when the hiker hit it on the nose (I believe that was the way it went, but don't hang me if I'am wrong) and the hiker got away with minor injuries. But in the Smokies some years ago (like 7) a hiker was attacked and killed. Two bears found near the body were destroyed. Human remains were found in there stomaches.
But , just my opinion, bears are the least of your worries. It's the mice that you have to be afraid of. Be very afraid!
