Even as a Canadian I find trips to gas stations and grocery stores in the US to be quite fascinating....
We have a lot of things in Canada that you just can't find that often in the States, and there are a lot of strange looking snack foods and brand names in the US that I've never even heard of.
When I went to Burning Man a couple years ago I ended up buying a load of candy and chips on the trip back so I could weird out all my friends with the American food.
It's fun realizing that you are from a unique country that has different things, with television and the internet I think we sometimes forget that a bit.
