Replying to Where should I visit?

My best friend and I are planning a huge road trip, and our main destination is Lake Louise. We are mostly going because it looks so fucking beautiful there, we just have to go see it for ourselves.

So like I said, this is a road trip. Its going to be happening in May of 09, or thats what we predict. I have no idea how long we are going to be on the road, but we are hoping up to 3 weeks (at the minimum!). Yeah, I said May of 09. We are planning wayyy in advance so that nothing can fuck this up.

For random and mostly obscure reasons we want to visit these places on the way (there or on the way home)..

Toronto
Chicago
Lake Ontario, Lake Erie, Lake Huron, etc.
The Mall of America
Lake Louise (Obviously)
Vancouver
Seattle
Portland
San Francisco
Utah!
Boulder




Why Im posting this is because we need YOUR help! Where else should we visit? What should we do when we get to these places? What are some exciting things youve done? Should we cross some places off our list? Etc.

Any advice from anyone who has done a trip like this would be awesome!
