OK, so one of my last unmarried friends has decided to tie the knot this summer. Rather than a "traditional" bachelor's party, he has decided that he and a whole bunch of his close friends should head off for a weekend at the Coachella Music and Art Festival near Palm Springs, CA. Coachella Website We're all flying into Las Vegas, spending one night (OK, that's a bit traditional for a stag party :)) and then driving in a rented van to Palm Springs.

While not something I'd normally do, I have to admit it sounds like good fun. However, I'm having a bit of trouble figuring what kind of survival or safety items I should pack with me. As my wife put it, "Nah, there's absolutely no opportunity for you guys to get in big trouble on THAT trip!"

Here's my thoughts on the parameters:
- I'm flying to get there, and then need to abide by the festival rules, so no weapons. Probably even no blades.
- We'll be staying in a motel while there (no crazy camping ala Burning Man)
- Most likely issues will be sunburn and dehydration
- Most likely major disaster would be major earthquake

I'm thinking of bringing, in addition to clothes, toiletries, etc:
- DR/AMK PSK.
- Two Nalgene one-liter bottles (bring them in empty and fill at water fountains. Try to always have one full one.)
- Small first aid kit, mostly for boo boos. I will have a CPR barrier, however.
- Lots of sunscreen and hand sanitizer.
- Broad brimmed hat and light-weight, light-colored, long sleeve shirt.
- Inexpensive knife, probably a SAK. I'll probably leave it in the motel the first day, and bring it along the other days if it looks like I can.
- Some cliff bars or something similar, so I always have some food available.

What am I missing? Anyone been to this, or other festivals like it? Anything I'm desperately missing for spending a few days at a concert in the desert? Should we bring a separate mode of communication beyond our cell phones? (FRS radios? Other?) I don’t want to leave myself or my friends completely at the mercy of the concert organizers if something goes wrong. . .

Any thoughts are appreciated.
