One of my long term thoughts about the event is the BLM really needs to require those guys to buy and install ground protection mats to put on their gate road. Probably cost $300k for a mile of the stuff or $10 per participant.
I’ve never been. But the feeling of being stranded with no possible way of leaving would have me going crazy in about 3 hours.
But why rain? There's a road leading up there, right? (or at least somewhere near the festival grounds). Most people will come by car or RV. They can still drive on that road I'd think?
If the festival grounds turn to mud, well... maybe a little detour to get back on that road.
(personally I'd be in no hurry to leave. But if you wanted to, what's holding you back? Organisers saying "road closed"?)
