We drove from chicago to Vancouver a few years ago. We ultimately ended up on Vancouver island. We drove up thru South Dakota and Uo to Wyoming through Yellowstone and then up through montana thru glacier into Canada. We went to Banff and Up to Jackson and then across BC. But instead of heading into Vancouver we went north and came down through whistler to get to Vancouver. It was a glorious trip. From Vancouver we drove south to annacortes to get the ferry into the San Juan islands and then to Vancouver island and Victoria, one of the most beautiful cities in the world. We drove out to visit our grand daughter who was going to boarding school on Vancouver island. Coming back we were running out of time and once we got back into Washington state we just booked it home. But if you have lots of time consider heading south to the coast of Oregon which is incredible and then heading east through Reno or Vegas, Arizona with all its wonderful sites, etc. we could easily spend two or three months driving around the west.
