Kemp

One of the adventures I'd like to try is the flight described in John
Joss' book "Sierra, Sierra" from Port Angeles, Washington to Yuma,
Arizona.

Hopping the wave from Mount Olympus to Ranier, Adams, Hood, Jefferson,
Sisters, Diamond, Scott (Crater Lake), McLaughlin, Shasta, Lassen, and
onto the Eastern edge of the Sierras. Maximum altitude climb at
Whitney and downwind glide into Arizona.

From the northern border of the US to the southern. Start at Sunrise
and end at dusk.
