It all depends upon the train od thought that you operate under. Before I had CCDW, I used to OC everywhere and it allowed me to help educate a great many Kentuckians on their 2nd Amendment rights, some loved the idea, others not so much. *LOL* Once I got my CCDW though I had a second option at hand, one the gave me even greater tactical advantage over a potential Bad Guy, the advantage of concealment.
I'll agree with you on the fact that OC would present more of a "presence", so to speak but people see things different ways. Apparently they prefer CC over OC in that setting. I, myself, prefer CC over OC unless I'm in the mindset to educate others that I encounter "out there". *LOL*
I'll have to look this new shop up the next time my travels lead me out west.
