I reckon the first day of deer season would alarm many Brits if they happened to be passing through Kansas Wednesday. The sight of so many heavily armed people, (right down to juveniles) to people from a country where most police don't carry weapons might be intimidating. The next 10 days won't be a good day to rob any small town banks either, as about half the population will have loaded .243 and 30.06 rifles in their vehicles, the perpetrators wouldn't make it far.
I do not hunt, I have leased a substantial portion of the families property to 6 hunters from Louisiana and Mississippi to hunt. My farmyard looks like we are preparing to invade a small nation, as there are trailers with deer blinds and stands, 4 wheelers, and even a camo painted Japanese mini-pickup.
Deer season is always stressful, because not everyone hunting really is smart enough to be lugging a high powered rifle around. Typically, I try not to walk too far away from my pickup, and don't venture out very early or very near to dark. Since we are overrun with deer, hunting season is a necessary evil, but I will be so glad when it is over.
