I saw that someone else lucked out with finding someone leaving J Tree Thursday morning who agreed to give them their spot. If anyone else is so inclined, please let me know. I will be arriving Thursday morning and leaving Saturday. I will buy you beer. And give you a scarf. And goldfish crackers.
I have a campsite at Black Rock that I reserved online for Thu-Sun, but no longer need. I realize it's less desirable than camping in the park proper, but at least you'd be guaranteed a spot. $45 for the three nights.
