I was out in Wyoming visiting my cousin and we walked into the local Post Office. There was a guy with a 10gal hat, revolver and a belt full of ammo......buying stamps. Remarkably, no one was killed !!Federal judge: Post Office violated man's rights by banning gun from parking lot - The Denver Post
I thought all federal property was a no go regardless of whether or not firearm was concealed or locked in trunk. This is good news.
