Made it up here. Found a fantastic dispersed campsite about a mile or two west of the venue for tonight. 10+ camp spots. About 20 min all unpaved backroad drive to the venue from this spot. It is quiet, no-one else is here. 4G service is enough to set up my wifi hotspot. Not sure if its National Forest or State Trust, but I have permit for Trust, so am good for the night.
GPS coordinates if anyone else needs a spot tonight: 35.137550, -111.731730
