Even in states where open carry is not against any laws and concealed carry is legal with a permit, there are plenty of counties and cities with laws against open carry. It's not as serious as a state or federal violation, but it's there. The ATF website has links to state laws, which also contain any city and county laws that are reported. Know your responsibilities.

That 66 looks pretty nice. I'd probably opt for a semiauto for carry, if it were legal here and if I decided to excercise the right, but a revolver can't be beat for reliability.
