next month (yes, in july) there is the 'badwater ultra', where contestants pay a hefty fee for joy of running from badwater to the Whitney Portal (135 miles).
That's right, entry fee is $995
And you thought a honda generator was expensive?
When I visited Death Valley 2 days ago, I visited the following campgrounds (scouting for a future visit):
Emigrant - empty
Texas Spring - one RV
Stovepipe Wells - empty
Thorndike - 2 cars, one truck with camper in bed, no tents or trailers
Mesquite Spring - empty
Furnace Creek - closed
Wildrose - empty
I'm sure there will be even more empty slots in the next couple of months. It was 117F two days ago at furnace creek. Oh, and if you stay somewhere close to furnace creek, the furnace creek ranch sells shower/pool passes for $5.
