I think road construction is a GREAT idea, but I think that Bill Vigger's
idea makes things a little too easy. I have no objection to roads being very
expensive to build - they were (from what history I know).
As far as Thomas Hudson's objections, to build a road I think it should be
required that the action be performed in each square. I agree that you
shouldn't be able to build into unoccupied land.
