You really do need to be wary of buck deer during the rut or mating season. They do crazy things like attack humans. Have heard many stories of hunters being attacked by deer during the mating season. That is when they run infront of cars usually chasing does. If a doe runs across in front of your bike or car, take caution as the buck may be chasing not far behind. Here, mating season is usually late fall to early winter but can extend to Jan depending on the winter.
