There is a site called VMF Member Locator where you could input your state and see the members there. However I suspect it's been abandoned/forgotten or something. All I get there is "access denied" messages. You can try it- VMF Member Locator
Maybe someone knows what's up with it?
We used to have a locator map on frappr.com but since frappr went belly-up this year, that was that. So asking for a roll call may your best bet. Carry on.
