Being in a Club, after midnight, in any City, puts you in more of a location (Minus your CCW) to get killed by gunfire, than practically any other place.
So smart locations are good, always carrying a Hi Cap pistol is good, shooting a sport like IDPA can not be bad either.
Spending your formative years in inner City's? Anywhere, can't be bad either.
Having a person with you, who you would die for? Turns you in to a very dangerous individual when threat comes to visit. With or without a gun.
