Hey,
Yours would be Veet Voojagig's Ballpoint Planet: Wormhole #2 and then your (state). Wormhole #1 is in California and maintained by my sister, MtnFrog, when I'm not there. You can use as much, or little, of the text as you want. Huntnlady did a version called The 9 to 5 Pen Exchange, where you had to solve a puzzle. She just archived it today.
It would be cool to have at least one in all 50 states and some other countries.
So all it takes is to hide a cache that connects to your wormhole?
