It was my understanding as long as I had my concealed for whatever state I'm in, which happens to be Oregon that I could carry where ever I wanted. My coworker though differently and said no, well I looked it up and found this, didnt know how trusted the source is so i thought i would ask on here.
It is unlawful to possess a firearm loaded or unloaded in a public building. “Public building” means a hospital, capitol building, a public or private school, college or university, a courthouse, city hall, or residence of any state official and the grounds adjacent to each such building. This restriction does not apply to individuals licensed under Oregon law to carry concealed weapons.
