  A problem with this is that the river presumably goes all the way around the earth. Otherwise you could just travel west until you found its end. You really need a donut shaped earth, a sphere doesn’t help much

  Crossing oceans, which are continuous with the river, seems to make this about as meaningful at tunneling under the river.

    I feel that leaving Koningsberg is already breaking the rules.
