A coast-to-coast flight originating from Spokane? Spokane is in
eastern Washington, not far from the Idaho border. Must be nearly

My mistake. The author called the flight "trans-continental" and
"across America" -- which my brain translated into "coast-to-coast"
for some reason...

Oven cleaner is my bet
