Nut cases are the worry. I have a retail store in small town Montana. Yes we have the nuts travel thru these parts. Last summer i had one. I threw him out, had about 12 shoppers, I was ready for him to bring out a weapon. I was lucky. I was ready with a bat and a pistol. I have not use either but I was thinking ahead about this type of guy. I am just so glad I live in a town with no stop lights and few and far between for nut cases.
