I saw something in y backyard last night?!?

Ok I saw something in my backyard yesterday and it was very wierd to me and I can't figure out what it was. Ok so it was snowing, and i was washing dishes when I looked out my window in front of the sink and I saw the outline of this huge thing. It was like a man, maybe 7-8ft. I have a big yard, and he was creeping along the outside of my fence. He was in total black, it looked like fur. So I kept watching and he went into my neighbors yard. I went out later to look, in the dead of night, and i found a footprint, not overly big or small. I live in a very suburban part of New York so i highly doubt it was a bigfoot. Any animals it seems to act like? It was walking on two legs so it is a bipedal and it kind of had a slouch to it. Any ideas what it could have been. My guess is that it was a brown bear from the woods that came through yards.
