Well, this wasnt just a couple hundred yards from the house. more like two or three miles. Im pretty sure that most people would use the four wheeler even with a deer on it instead of trailing behind for a couple miles.
Two or three miles should be no problem for a young person. If you had offered to carry your girlfriend part of the way she probably would have been even more impressed and you might have "scored" bigger points with her than you did by shooting that buck!
