CD Exchange 2010
After mulling it over and looking at various suggestions, I like "Road Trip". This is pretty wide open: Modes of travel, leaving or coming home, exploring foreign climes. The basic theme is movement.
Marscon is coming up, so I hope our various far-flung correspondents can play! I'll have one ready by then.
Let us know if you're playing, so we know how many CDs to burn. I'll make a few extras.
