Vancouver to Penticton - the Washington way

Me and the Wife need to go to Penticton BC for a family birthday Gathering. Ride up Saturday, Ride home Sunday.
Unfortunately, I hate the usual way to Penticton, especially the ride from Vancouver to Hope. So we have decided to take the long way round via one of the best roads in the Pacific Northwest - Highway 20 in Washington.
The plan is to leave early Saturday morning and take old Hwy 99, which pretty much follow the I-5 and allows us not to travel on the I-5, down to the beginning of Highway 20 near Sedro Wooley. Then it's 120+ miles of Motorcycle road twisty bliss as we follow Hwy 20 into Winthrop, Wa. where we will stop for a well deserved late morning beer. Then we will continue on the 20 until we begin to head north towards the Canadian border on Hwy 97. The main border is at Osoyoos, but there is a small border a few miles west that we can access through some quiet, beautiful backroads. I hope to go this route as there will be less traffic for sure and much more a scenic ride. After crossing the NightHawk border (literally 2 houses in the middle of nowhere - open 9-5) the plan is some back roads into Penticton, just in time for family festivities.
The ride home via the Crowsnest is the plan. A pretty good road, but have ridden it so much that, if we can get up early enough on the Sunday, we may avoid and take the Hwy 20 route home as well.
If anything just remember this.... HIGHWAY 20!
