Porcupine rushing past the camera
Well maybe not rushing, but fast for a porky. I've been trying to get a photo of one up a tree eating bark and will try again next spring.
On another note, I have been searching for a large ant hill to place a long term camera to find out the types of animals that dig the ant hill apart. Found a nice one but it had been torn up in the middle recently, plus it's out in the open and can be seen easily, so it's out of the question. Need one that's out of the way from humans if I'm going to leave a camera on it for months at a time.
