Beautiful place! We went there last year (in the car...).
How does your bike reacts to different elevations? Our car (Subaru Legacy GT Spec.B) was not effected (turbo charger) but I can imagine normally aspirated engine should loose about 10% of its power every 1000 ft above see level...
Did you feel any of it on your bike?
2008 328xi (manual)
2009 R1200R, black
2010 F800ST, champagne
2013 R1200RT, midnight blue

This was Hwy 89, north of Yosemite through the Sierras almost exactly a year ago (1 year + 1 week). The highest road elevation was 8,320 feet and I didn't notice a thing, even on my loaded-down 800GS.
Temperature (end of May) at noon was a balmy 21* F.
PS- I'm no math whiz, but if you lose 10% of your power for every 1k feet above sea-level, how do you explain the guys who ride their bikes to 14k foot elevations in Colorado? They should have what...-40% power?

Last time I rode that pass was on a bicycle...down to 395 and back up. The famous Markleeville Death Ride (aka, Tour of the California Alps).
Going up there this summer with my 13 and 14 yo sons. They're going to descend to 395 on downhill skateboards. I'll trail them on the R (for safety from passing cars), with HD camera of course...should be fun.
At the 11,000' summit of Beartooth Pass in Wyoming last summer I didn't notice much power loss, though I wasn't really trying to scrape pegs up there either.

That's unreal! I can't think of what would possess someone to ride a bike up that hill.
I've got to admit though, I was blown away by the scenery between 395 and the summit. And that's saying a lot, I lived in the Canadian Rockies for a couple years. But the back side of 89 near 395...I simply didn't know there were places in the US with alpine scenery like that.
That video is from Tioga Pass (Hwy 120, a good distance south of 89). Amazing video but I've got to admit, I got pissed off at the kid when he road right towards the oncoming cars and passed behind them. Probably scared the crap out of them. I hope your kids will at least stay on the right side of the highway Contra.

Oops...yes, I meant Hwy 120. Sonora Pass is steeper and would be a lot harder to skate down.
The kid in the vid (Liam Morgan) is a pro skater and probably the best longboard rider in America. Lives near us and rides with my kids sometimes. He is a little too crazy for my taste and I don't let my boys go down the hills he rides. I once watched him dive over the hood of a car that came around a corner and surprised him when he was on the wrong side of the road...
