I guess the rut has begun.

This happened to my uncle 2 years ago. A buck saw his own reflection in the tinted window of my uncles van and began thrashing the van. My uncle startled the buck when he came to investigate. The buck ran onto the lawn where he saw his reflection again in the large bedroom window and charged it. There was a nose print from the impact all the way up the window and onto the bottom of the gutter, with kick marks all over the siding.

Beware the Kung Fu Bucks!
