You never know when you are going to need the firearm but when you do need it, it can mean the difference between life and death. Why wouldn’t you carry one on a trip? Most trips I never see it and it is in the front case between my knees. You cannot predict what situations you may encounter in life. I try to be ready for all of them I can imagine.
In this modern world we live in, where we give long leashes to crazy people, make excuses for previous dangerous/sociopathic behaviors and actions, empty our prisons early and have a general social disdain for once commonplace morals and values, there are, in fact, thousands of opportunists walking the streets and highways. The police cannot be everywhere nor should they be. Your personal protection is your responsiblity. Get handgun training, practice regularly and be ready to act to save yourself from someone who wants what you have and will kill or injure you to get it. Calling 911 will be worthless in an emergency.
I do not know about you but I am too old to take a beating and too young to die. I do not look for fights but I am going to protect my property and self, period. In Texas, major crime has dropped considerably since conceal/carry rights of Texas citizens. You rarely hear of CHL citizens shooting someone without cause and there are hundreds of examples every year where crimes were averted because of citizens having a firearm. A better question would be, “Why not carry”?
