on Saturday while helping an old lady with the auto mailing machine in the Post Office.
The dreaded black snuby shilloette surrounded by the slashed red circle was on the bull board about 2' above my head and normal gaze.
It said no yadda yaddas etc in Fed Buildings and prescribed severe punishment.
Memory may be failing but recall discussion here or somewhere else a few years ago that indicated since most POs are leased by GSA they technically do not fit the criteria ... not gonna bet much on that one.
The other, according to my recollection possibly more substantial, exception to the then stated rules was that folks in hunting regalia or involved in other legal business(like getting my mail) were, by oblique omission, authorized to carry.
Having worked for the Feds I know that often their regulatory reach exceeds their regulatory grasp ... IOW they may be bluffing but their employees mostly do not know it.
Normally I could stash it in the car ... but the PO is over a mile from my home and part of a 3-5 mile walk each day. Port Angeles is a mellow town but I sometimes go at night.
