Unfortunately, a lot of US citizens are ignorant about your awesome country. I had a car accident in extreme northern BC back in 1994, and everyone was extremely helpful. I'm 40, so, a lot of my generation's first taste of Canada was from the movie, Strange Brew. I was shocked that you guys really do say eh alot. :-)
Most importantly, I would like to welcome you to this forum, and to thank you and your fellow Canadians for your hard work and assistance during Operation Yellow Ribbon during and after the horrible attacks of 11 September 2001.
