Every day, everywhere I go. If OC is not allowed, I leave it in the car. But I OC in my car EVERYWHERE (castle doctrine) and even in my own yard having fun or doing chores. All of my friends consider it normal and don't even bat an eye now. Some are even considering it for themselves. Many don't yet because I have encouraged them to do it AFTER some training including marksmanship, weapon maintenance, proper draw techniques, legal use of deadly force, etc. It is a big responsibility and I train almost every day including watching training vids on the law, UNloaded practice drawing, loading (empty mags), reloading (same). I even practice in the utter darkness at night, drawing, loading, reloading, teardown and rebuild including doing all of the above one-handed with each hand. The good news is that I will likely never need any of these skills
I just like maximizing my preparedness.
