Here in NC, many counties ban firearms in ANY buildings with municipal or county offices. y county is one of them. So I could not carry while voting, even though my polling place was a fire station, and NOT a "sensitive building" as it contains no police, courts, or jails.
But I DID pick up two "I Voted" stickers--one for each of my Serpa holsers. One for the Glock, and one for the 1911, and I will wear them proudly at the range, while OCing everywhere else, and while going to OC-related events.
I envy you folks who live in states where the government actually trusts law abiding citizens to carry in government buildings. Here in NC, they are afraid of armed law-abiding citizens...
