When I first moved from Canada, to Florida (2003) Citizen in 2011.
I was amazed at how nice the average American was, everybody you speak to, smiles and speaks in reply (In my case any way) and fist fights are just for drunks and bad people?
What's with that, having worked in the Clubs in Liverpool UK, part time Thur/Fri/Sat nights (young Family to support. 1960 till 1964 at The Cavern Club, of Beatles fame) if asked when were you last in a fight, some would look at their watch!
I now carry a Glock 19, every day, it is in my ratty old plaid gown pocket now, and an IPhone.
Have not shot anyone yet, but my last physical altercation was in 2004. I was 69 years of age. Did not use fists or feet, just some redirection!
Knowing how to use a gun, yes, that's good, being involved in some straight out and out violent encounters, that's good as well.
Being savvy to street encounters, that's really very good! Excellent!
Heads up, be observant. On your feet, and behind a steering wheel too!
