Whwn i was little i would always write joke postards. I wrote maybe the town name but then only explain what the house looked like. Like the only yellow house on the (roadname) or whatever. The postcards always found their way as far as i remember. One time the postcard didn't make it, and i was bummed. Then it arrived month later and it took a detour trough multiple countries. As an adult i wonder why that worked, and i doubt it still will and if it helped that these letters were clearly written by a child.

As someone who works as a courier but is sadly not a postal worker (Lucky unionized bastards) I can say with certainty that after awhile you start to develop a weird sixth sense for just where places are, it's weird.
