Camping at Furnace Creek December 24-29, 2007. My wife and another couple will be with us. ANy wheeling should probably in the moderate range. Not sure how the other couple is going to take to it!
Glen, I've done the Racetrack Playa/Saline Valley Warm Springs/Eureka Sand Dunes trip a couple of times, it was GREAT! The 'wheeling is in the moderate range as long as the passes are not snowed in, but you are a loooong way from civilization. This was in January of 2002:
Racetrack Playa
Camping at Racetrack Playa was cold...
Coupla days later at Eureka dunes it was much warmer.
First view of the Eureka Dunes
The hardest part of Steel Pass between Saline Valley Warm Springs and Eureka Valley. This it the stupid line, you can drive over the rocks and stay level.

What happens in Saline Valley stays in Saline Valley...
