By the numbers:

• 400 miles from Walla Walla to Boise –  671 total miles
• highest temp:  93.
• highest elevation: 4245 feet at White Bird Hill, between Lewiston and Meadows Valley.   With a 7% downgrade off that peak we could smell the brakes getting a little hot.  Then Peg figured out that the letter “B” on our Prius gear shift stood for “Brake” and is a special mode, like down shifting on a manual transmission.  We used that on later grades and it works great.  After having the Prius for 7 years I guess its good to learn one of its more useful features.
• 3 states : Washington, Idaho & Oregon.  Total for the trip: 3
• Licence plates spotted:  6 new states and provinces – 21 total for the trip
• 3 new National Park sites and/or stamps:  Nez Perce, Lewis & Clark Trail, and Big Hole Battlefield. – 5 parks total for the trip.
• 1 major river crossed:  The Snake – 4 times.  (There is a reason they call it the Snake River.
• 51.8 miles per gallon so far.  Filled up once at about 400 miles: 8 gallons.
• Also today we crossed the 45th parallel which is the point exactly halfway between the equator and the north pole.

It’s late and I have no other thoughts to share tonight.  Tomorrow we stop by City of Rocks and end the day in Utah
