Lots of Opportunities along the way. Some I would suggest:
1. Of course follow Canada 1 through Banff, Rogers Pass & Revelstoke. Follow the Ice Field Hiway to Jasper if you have the time
2. After Revelstoke, travel Rt 97A south through the beautiful Okanagan Valley, BC, look for Ogopogo inthe Lake, then into Washington. Continue south on US-97, Detour to Grand Coulee Dam if you like.
3. Then down US-97 to Lake Chelan. (Check out <<<golakechelan.com>>> for local stuff) Take the Ferry (or float plane) uplake to Stehekin. I can arrange a free driveway spot right across from the Boat Landing in Chelan. You can stay with a native, she speaks American, Canadian and Strain'.
Take in the local wineries, Tsillan Winery has a new resturant with incredible Italian food, and try their Sempre Amour. You will want to take home a case. By April, I might even be there....
4. Work your way south to the Mary Hill (Great camp ground there) crossing into OR and continue across the Columbia and drive the scenic RT 30 through the Columbia River Gorge on the south side, then cross back over to White Salmon closer to Portland. Lots of camp grounds on the OR side as well.
Guarantee: You will never forget Lake Chelan, especially if you go uplake, or the Water Falls on the Gorge route
