A couple of open carry encounters I have experienced:
First one in Matamoros Mexico, early 1980’s, every block had 3 to 4 guys walking together with what were probably AKs (I don’t know because I wasn’t really into small arms at that time). Each group was in matching uniforms. What set my situational awareness off was no two groups were wearing the same uniform. Bottom line is it made me uneasy.
Second one was at my son’s house. His friend was coming over riding a motorcycle. Son was predisposed, taking a shower or something, so told me to let his friend in when he got there. I heard a motorcycle pull in the driveway. I answered the door. Standing in front of me was a young man open carrying. I had never met this friend before, so I asked him his name. It was the right name, but have to admit I was on high alert until he said the right name.
With that said, I legally open carried in Florida yesterday - I was out fishing. No notable catches except I lost an 18-20" Spanish right at the boat. Was using a circle hook on mono. I believe the teeth got the opportunity to cut when I went to haul him up into the boat. Taking a dip net today
