I rode through the newly revamped Furnace Creek Campground in Death Valley last weekend. It's been totally revamped for the Diesel Bus RV crowd... Too bad it's not rustic like it used to be.
There is still tent camping, but now you park in a "space" and have to walk into your campsite area. I'm sure if you rode your bike over to the tent they'd have a conniption fit... They've also removed a number of the trees which of course provide needed shade. Also watch for pitching your tent in a low spot. It looks like all the new asphalt has created even more flooding potential for campers.
