Just looking quickly at the map it looks like there are more members east of the Mississippi than west. As far as a regional event maybe hold a few v/s one for each state. I bet an event in say Ohio would draw most of us on the east half of the country. Colorado seems like the central point for the western half. Planning would be very important for some. There are many reasons such as work scheduling, finances, etc. that need to be taken into account, so the more notice the better.
