Anyone know of any reference as to whether the St. Lawrence Seaway is still running? (it includes the locks along the St. Lawrence river between Montreal and Lake Ontario and the Welland canal that bypasses Niagara Falls). It carries a huge amount of cargo, so plenty of people would want it running, but in a dystopian world that doesn't guarantee that it has stayed open.
The upper part is in UCAS lands, but the downstream end is in Quebec -- when Quebec was in its isolationist phase, shutting down the Seaway would have been devastating to the economy of many locations around the great lakes, so I'd guess that keeping it running would have been a bargaining chip Quebec would have used to be otherwise left alone. But since they opened up, I could imagine one of the megas taking over the whole thing and monopolizing Great Lake shipping -- but even in the ShadowRun world not everything has to be linked to the megas!
I was just working something up for my game, and can make up whatever I want, but if there was something hidden away in one of the source books that I missed during my 20 year hiatus from the game, I'd love to hear about it.
