We all know that anyone can ship a firearm to himself in care of an outfitter for example. This is perfectly legal as long as the box or case is not opened and he does not take possession of it. I recently found my self going on a trip, without an address to ship to. I was on the verge of cancelling rather than trust my gun to the airlines. A firearm (long gun) can be shipped to any post office. Addressed to yourself, general delivery. It will be held for thirty days.
