Gone Fishin'
How bout: Race to the other side
Make a map showing the story of an alternative Trans-Continental route (can be a railroad or a highway). The catch is, it must involve some kind of competition between 2 or more countries or companies (can involve 2 separate routes or different starting points on the same route).
I like this one, although I feel that we might be limited by 'Trans-Continental'. That said, I vote for this as it sounds fun (assuming this is still valid to vote for come the next round).
