USPS Carrier Pick Up
The best way to deal with areas where armed CWP holders are not welcome is to avoid them wherever possible.
One such area is the post office. I recently found out, however, that I can print postage for my priority mail packages at home, and request that a USPS letter carrier come pick them up. As an added bonus, the postage rate is cheaper than if I drove it to the post office myself.
I’ll be spending a LOT less time at the post office.
