My experiences have taught me that every animal is different. Some could care less while others will avoid the area like the plauge. Even deer that will spook one day may not the next. Now i am not currently studying whitetail psycology but this is what i have gathered. Some of the biggest deer i have seen was while i was running the combine while deer were feeding 1/4 mile away. We had fellas camped on my land a few years back in a draw elk season. They guys were sittin around camp in the afternoon and a cow ran right through camp and back into the bush. Of course the guys never had a rifle ready to rumble so they were useless as tits on a tomcat. One of the best lessons i have been taught the hard way is expect the unexpected. Murphy's law if it can happen it most likely will. I would sooner be safe than sorry and leave my vehicle a good distance away but don't be suprised if there are a few animals hangin' around near the vehicle. Sometimes i just think curiousity gets the best of them.
