Congratulations on the mileage. Good showing. But I find it funny how perspective changes everything. 4100 feet in elevation is NOT a mountain. You're still 2K Ft below my HOME elevation.

A mountain is driving through the Eisenhower/Johnson tunnel on I-70 (~11K feet)

. But you get one heck of a stretch to coast on the other side! Well, the change in elevation from my home to the tunnel isn't much different than your drive! As I said, it's perspective.
It will be interesting to see how the HCH does along this stretch. Ever since my '99 Odyssey, I have gotten used to cruising over to the tunnel at 80
MPH with ease.
