Marlin,
We where actually talking about this at our last Colorado VX meet and really couldn't come up with a "typical" VX owner. I thought that since these things where so odd and "designerly" that there would be a bunch of people in the design field (artists, architects, graphic engineers, etc.) attracted to them. I know that we have a few of those types around (heck, I'm an architect), but we really have a very diverse bunch of owners. From policemen to software engineers, students to retirees and all different ages.
The great thing is that the VX attracted us to it for some reason, and even with our motley crew here on the site, we all seem to get along (for the most part).
