I keep my jack and spare tire in the car where they belong. No need to carry them around 24/7. I keep my guns at home unless I'm hunting or at the range. Only a coward would think they need to carry a gun 24/7. Armed 24/7 is either a fashion statement or something you really need to discuss with your therapist.
Not at all. Here's how it happens. You get your CCW, and you start carrying your firearm on and off. Then, on one of those days you're not carrying it, you're listening to the radio and they've arrested a guy in the next town over, crazy as a fucking loon, who was planning on shooting up the Walmart. And you think to yourself "Why the fuck don't I have my guy today? You know how karma works...the time you really need it, you won't have it." Since you're already used to carrying it, it's no big deal to make it part of your routine...wallet, comb, keys, firearm.
