I made one ornament for Media, PA and one ornament for Sparta, NJ. One the back of each ornament is a map of Media to Sparta. Derek and I have traveled thousands of miles up and down the turnpike and since we'll have our own tree next year these little ornaments will be a memory of our travels (not that we'll ever forget the countless hours we spent traveling to see each other).
These ornaments are SO simple! I got two little stars from Michaels for about a $1 (the ornament doesn't have to be a star -- any flat ornament will do) and printed out the maps from google.
