Canadian American RV Culture Difference

Well the way I see it , there isn't enough difference to worry about.

I don't worry about it, I enjoy it! We don't go down to the US just for the cheap gas (well, relatively) or cheap booze, and sights like the Grand Canyon, but all those little differences that make a foreign trip fun.
The funny way many of them talk, the different sayings, the different stuff in the stores. The blandest beer in the world, and some of the best sold in the same pub. The size of the meals, nachos for $3.95. Happy Hour! Amazing conversations about the state of the world in a bar in Shelton Montana at 1am. Sleepy, dusty towns at 1pm with blues music on the radio. Polka Hour on the radio somewhere a little north of Omaha. Incredibly entertaining radio talk shows of a particular slant. The amazing amount of 'church' programmes on the radio, totally unknown where we are from. Trying to understand the accent of a very friendly waitress in Minnesota (and you think many Canadians say 'aboot') Trying to explain to a group of very nice ladies from Iowa that they had much colder winters than we do at home. Trying to convince a very educated business man in Montana that we would have to head South rather than north at some point in our trip to get to Toronto! Wondering why anyone would eat 'grits' and what 'hush puppies' are made from. Trying to convince a lady in New York State that Canada had a west coast. Staying in a fantastic log hotel in Wisconsin for $29 a night with a huge indoor pool just outside our room in a beautiful atrium. Wondering why a town straddling the Wisconsin/Michigan border would have all the night clubs, bars, gentlemens' clubs etc on the Wisconsin side and nothing on the Michigan side.
I just love seeing things like this. So many people want to travel to different places but still want to find the same as at home.
