30 years. I carried in my Freightliner long before Illinois had CC. I had an out of state (Washington State) CC permit which I was certain was useless in most states but which made me feel more comfortable. Thankfully I never had to use it.

Regardless of caliber or make or style of firearm you carry always keep two reloads with the gun. In a pocket, briefcase, purse, pocket, or wherever else you may wish to carry them. One reload is never enough if you have to use it.
