Just saw a piebald whitetail a couple days ago near me as well.
My most interesting hunting experience was in Maine on a bear hunt. We decided to spend one of the days taking a canoe down a local stream to see what wildlife we could spot. As we came around a bend we heard something in the brush on a high bank, so we started back-paddling to see what it was. Out steps a moose calf, and not far behind was a VERY nervous cow. Realizing we had just gotten ourselves into a potentially dangerous situation, we started putting some distance between ourselves and the bank when all the brush starts thrashing behind her. Cue one very large bull erupting from the brush, hot on the trail of the cow. So here we sit in a canoe in the middle of the moose rut, no firearm, with a bull full on chasing a cow whose only concern in protecting her calf from said bull and now us as well. I'm not sure if it really qualifies as a bluff charge, but at one point the bull rushed towards us into the water, stopping about 20 feet away and staring at us. About that same time, the cow took off downstream and he decided he'd rather pursue her. We crossed paths with them a couple more times but never closer than 150yd.
