Don't get to froggy with your calendar just yet.
I just suggested we consider swapping the start to Spokane area for the convenience of the travelers coming from the south and east.
Day 1, will probably be a late start, most first days are. Plus stopping for breakfast at a little airport in Spokane Valley. Lunch @ Harrison ID and then the spiral Highway both ways (of course).
Day 3 would be for you guys to make a run back toward the west side of WA.
5-6 hours of super slab would put you Wenatchee. From there the next day you could either do 2 or Hwy 20 back west. If deciding on 2 you could spend the night in Leavenworth. Lots of options. Wenatchee to Tacoma via 2 would be quick enough you could get to Nels that afternoon.
On my side of the state it would be Spokane Intl. If we start over here. Not sure about bike rentals here. If you are borrowing or renting it might be best to fly into the wet side and come over this way with Steve. My 2 cents worth.
$ell I do not care were it starts or really were it ends. Just as long as we get to see all the sights from two wheels. Plan on doing the same on the ride there and back again. Leaky Texas was a warm up but this will be a real ride. Got the itch figure by the time this ride comes around will be ready to scratch.
