It's kinda like going to a beach. If it's a nude beach, everybody's gonna stare at you and make you feel weird if you're the only one wearing clothes. Likewise if it's not a nude beach, and you show up naked - well, people are going to look at you funny too.<or worse>
In the 19th Century, it was kinda like a nude beach ie. everybody carried openly, and you might be feeling kinda vulnerable and odd in some places if you didn't do it too. Nowadays, it's just the reverse. Go with the flow.
Also consider the odds of things. How likely is it that someone will bump their car into your car, and when you go out to investigate, they start ranting and prove themselves to be a nut. Now if you're openly carrying a gun, they might even make a nasty false allegation about it. Hmmmmm...what's the liklihood of some situation like that unfolding compared to the liklihood of needing your open carry gun to save the day. I'd say that there's lots of the former situations, and only an extremely rare chance of the latter. Concealed - is the way to go. Life's a beach.
