When I first started smoking a pipe, and my first time at The Briary, I asked about tins with age on them, and Skip led me to a closet with a bunch of old tins with all having over six or so years on them, and he let me get whatever I wanted from it.
And, when I went to an old Tinderbox owned by this 70+ years old guy, when I asked why he didn't have any tins, he said that he couldn't sell them before they went past the expiration dates. He had thrown all of the old tins out with the garbage, ha ha.
Life is like a box of chocolates... ha ha.
