After driving all night, we arrived at Joshua Tree NP at around 2:30am. Tired, but excited, we looked for a place to camp - and found nothing. After driving through all the campsites for another hour and half, we finally pulled into a hidden (but legitimate) site at Belle. I think that campsite has my name on it because every time I think there are no sites left, we find this one spot open, waiting for us. It's a great site too - protected from the wind.
