I saw my first BEAR on the trail (not the AT, but a side trail).
Of course it was in New Jersey, and it was in someone's back yard trying to get into something that looked like an old refrigerator. I took a couple of pictures, but at something like 30 yards at dusk it just looks like a black ball next to something that looks sorta like a kitchen appliance.
Actually, the night before I saw a pair of eyes near the bear box at the shelter where I hammocked which probably belonged to a bear. I was just out watering the foliage, looking around with my headlamp, and there he (she?) was, staring at me. When a dog barked down in the valley I saw the eyes turn briefly, then continue their stare down with me. When I was finished I quietly returned to my hammock and back to a deep sleep.
Unfortunately for me it was more of a "Well finally!" moment than anything else. I guess I've just gotten used to the fact that they're out there, seen or unseen.
