My bike tour routes often take me through tiny towns, many of which are extremely remote, have absurd names, or are otherwise worth commemorating passage through by stopping at the Post Office, buying a postcard (current price 23 cents), filling it out on the spot, getting it hand-cancelled so the postmark bears the town name and sending it to someone you know will take the time to get out the map and have a look-see where you've gotten yourself to this time. I was really, really sad to hit Moclips on a Sunday, when the Post Office was closed, because I know at least a few people who would have loved a card from there.
