Need Help Planning a North USA/Canada Roadtrip?

Hi everyone,

My family is planning a roadtrip this August that will take us from Toronto through to Vancouver, with many stops along the way in north central USA and western Canada.

Could you guys that are familiar with the following states recommend some key points of interest:

-North Dakota

-South Dakota [Mt Rushmore/Badlands]

-Montana [Glacier National Park/Going to the sun road]

-Wyoming [Yellowstone National Park]

-Idaho

-Washington

-Alberta [Edmonton/Rocky mountains]

-British Columbia [Vancouver area]

-Illinois [Chicago area]

-Minnesota [Minneapolis]

Some areas I've heard are must stops are listed in brackets, but I'm still unclear on some locations, and possibly how much time I should spend in each area. I plan to drive mainly from Chicago through I-90, and up into Alberta on I-15. On my return, I'm either looking at returning on I-90 or I-94. I have a max of 3 weeks to spend, so I'd love to visit the major tourist spots before looking into smaller stops.

Here is my full route so far:

1. Toronto to Chicago

2. Chicago to Mount Rushmore/Badlands/Rapid City (via Sioux Falls)

3. Rapid City to Yellowstone National Park

4. Yellowstone National Park to Calgary

5. Alberta Circle (Calgary to Edmonton to Jasper to Banff)

6. Banff to Vancouver

7. Vancouver to Seattle

8. Seattle to Glacier National Park

9. Glacier National Park to Fargo, ND (via Bozeman, MT)

10. Fargo to Minneapolis

11. Minneapolis to Chicago

12. Chicago to Toronto

Of course, I'd reroute this depending on other suggestions. Any route recommendations, points of interest, and general input would be greatly appreciated! Thanks :)
