Report 21792: Night Time Sighting by Motorist - South of Lupton

I was driving down rose City Road in Lupton Michigan at about, 10:10 p.m. and the road that I was driving on goes right through the lupton swamp. I seen something in the middle of the road. It was huge. I slamed my brakes on. and the closer I got the more detail I saw, and the faster it moved. When I saw it it was in the middle of the road but when my car got closer as I was putting on the brakes. The creature somehow was sudenley was on the side of the road , approximately 10 ft from where I originally seen it. I never saw it move it was just there all of a sudden.It was very Tall about 7-8 ft. all hairy, on the sides the hair was dark in color with a silverish grey top layer . with a chest span from back to front at least 2 ft. across.It was standing on 2 legs straight up.  At first this whole thing seemed unreal . I then took the closer look and that is how I got my description.Then out of know where it was gone.
