To the geographical center of the US Kansas/Nebraska. See how those $@&:);+/=#!!$&@#!=? lobbyists like doing business in cow pastures and corn and wheat fields. We could just use DC as a historical venue,move all the congress critters the hell out.
No matter where they moved it the press and lobbyists would follow. Soon you would have the equivalent of DC in Kansas or Nebraska. The only way to get rid of it is to send them all home to their districts. There is absolutely no reason they have to be in DC with technology.
