So I'm messaging you as you are perhaps what could best be considered V3's most prominent North America Modder.

How difficult would it be to put ports on the Great Lakes and turn the St. Lawrence into a shipping lane? I would expect this would be a Map mod more than event programming but, the ability to build/unlock the expanded locks around Niagra and the Sault Locks at appropriate techs/dates sticks out.

You've already done so much and have an impressive road map as is, but is this something that could appear on your radar for this mod or on another modder's interests that you know of?
