Seems the local constabulary in Ohio have a little problem figuring out the whole open carry thing. Please Visit Ohioans for Concealed Carry and follow the thread for More Info. I know some disapprove of open carry except under controlled circumstances, and feel that it is somewhat exhibitionistic and wont to draw unfavorable attention - in short it "scares the white people".
I can see this point and, in truth, would be taken slightly aback if I saw a gun on the hip of the guy next to me in line at the Giant Eagle. On the other hand, I don't think I'd call the police.
That having been said, I think the times have changed somewhat, and open carry is no longer beyond the pale, so we should at least refrain from criticism even if we cannot lend support.
