Thats pretty amazing. I hope you see him again sometime. Here in WI, I know of some people that have deer that'll come up to them to be scratched and itched. It seems like, if they are comfortable with you, they wont run off... and most deer are typically "herd" animals.. usually traveling in groups.. so, if he doesnt have a little herd of his own, maybe that's why he sticks around you... your his protection and herd... jsut a thought.
