I will be driving into Yosemite after a couple of days in Death Valley, using the Tioga Road entrance. This will be my first time attempting Half Dome, so I've decided to try and start at midnight or 1 am to beat the crowds and arrive on top for some more scenic early morning lighting.
If I arrive on a Thursday afternoon, do you think there is any chance I could snag a spot at Porcupine Flat, Tamrack, or Tuolumne to catch a few winks before sneaking into Yosemite Valley under cover of darkness? I've only been to Yosemite once before, but it looks like they have a no-randomly-sleeping-in-back-of-your-car policy. Is this enforced or will it be possible to park somewhere and sleep in the back of an SUV for a bit, assuming I don't get a camp spot for car sleeping?
This is my first time posting here, so apologies if this is in the wrong place. Thanks.
