Lewiston, Idaho
Gateway to the Poisoned Lands
It’s not the safest gateway, of course. But with the Utahns taxing the best roads, and what with both the Canadians’ and the Texans’ obtrusive oversight over their own paths to the Poisoned Lands, the caravan route from Lewiston to Minneapolis is the best way to get across the High Plains without official notice being taken. It also helps that Lewiston is at the confluence of the Snake and Clearwater rivers, and much more that seismic aftereffects from the Serpentfall created a series of natural dams that made the city accessible by sea, with a little help from engineers.
