And all that online QSL crap just isn't as fun as going to the mailbox and getting a post card from the other side of the world.

I even liked getting a card from someplace as mundane as Cornfield County Iowa if the graphics on the card were clever enough.
Tell you the truth, I don't even know how to use LBOTW.
