tried to google "geografical center of US" but so far no luck.... ...but I`ll try to see if I can find out where it would be in US
I would be all for the geographical center. Probably be somewhere close to me. But to be fair, it would probably need to be more like a "center of gravity'. IOW, find out who would be willing to make a commitment to going and then find the center point in relation to that. Or, just pick a place where you think most people might be more inclined to make the trip and stick with it.
