The problem is that they are scattered across the US -- California, New Mexico, Colorado, Illinois, Michigan and Virgina (I think in the last case). But I'm the only one in California and if I'm right about one being in Virginia, he's the only one there. The two in Colorado are from different gaming groups (High School and College vs. early days at Motorola), and both groups are represented in Illinois. And then there are two different cities in Illinois, and two different parts of the state (UP and LP) in Michigan.
It would be almost tempting to try to set up a gathering on Skype or something and see if we could get a game going.
Of course, finding time to do that could be a bit tricky.
