I always thought the US-Canada border should be vertical instead of horizontal, running from the Arctic through Saskatchewan and North Dakota for example down to the Gulf of Mexico. Having grown up in Eastern Canada, spending my Navy time in the Eastern US and living in the Pacific Northwest, with relatives in British Columbia it just makes more sense. Politically, environmentally and from a population density stand point we're much more in line with Western Canadians or they're more in line with us, than the East coast of either country is.
Texas - Alberta=steers and oil wells
Saskatchewan - Midwest US = farm lands and low population densities
West Coast US - BC = tree huggers, outdoorsy types and Liberals
VS.
Ontario - Illinois / Indiana = Huge cities surrounded by farm lands and tundra
Quebec - NY State, = Large cities surrounded by woods and lakes, some mountains
New England, Eastern Seaboard of both countries = fishing, lobstermen, water sports (ahem), Maritime culture..
Just makes more sense to me.
