Congratulations on your first open carry.
With the exception of the lapel mic being 'off', it sounds like a pretty sucessful outing. Dont concern yourself with being long winded- Its certainly more engaging when there is sufficient detail to take the reader there.
As it has been stated a few times before, most people react to someone open carrying with the assumption that the armed person is either police or otherwise 'authorized' to do so. Others arent even aware, unless it is pointed out to them. Its because of these things that the police are seldom summoned.
You dont say what you carry, what kind of holster, or how you are carrying your ammunition. Just curious- if you dont care to say,.. thats cool too.
