Here's my guesses and interpretations as to how to best help. THIS IS MY INTERPRETATION FROM OTHER NOTES ON THE EPLAYA.
What I'm reading is that folks who showed up at Hagey's expecting a place to wait for a ride, etc, are all being pushed out - whether that's "Leave now" or "leave real damned soon" isn't clear from the notes.
So the first and foremost thing we can do is to pick people and gear up from Hagey's. The quicker we get these folks onto the playa the better. If you have any spare room at all and are going thru Reno, it's probably best (my guess) if you call Hagey and see what you can do. He posted his numbers after the first disaster as: HAGEY at 775-358-5080, FISH at 219-614-1835, SANTA at 219-614-1835. From this note: DO NOT CALL unless you are inbound or have some specific contribution, it sounds like they are going crazy enough already without well meaning calls of support or chat. I'm guessing that the gate will be pretty flexible with early arrivals to accomodate this disaster, but that's JUST A GUESS on my part.
An address was posted elsewhere: "through Tuesday, pick up people at 1350 Breaker Way Sparks, NV 89431 near the N McCarran shopping centers (Safeway, Target & many more)." As noted here, BE DISCRETE and don't clog up the roads trying to help. Hagey says here: "but park away from here, and NOT park on this street, walk down here"
I don't know if people who arrive from other directions running shuttle trips out to Reno and back is likely to be helpful or not, it may be worth a try. I plan to visit the on-playa BRIBH and ask.
The other thing is, I'll bet they need money. I expect that people who showed up in Reno expecting a free night's stay and a pot of beans to share are being forced to stay in motels, buy dinner, and maybe pay for taxis. From another thread, "Hagey has given out his official pay pal account: email@example.com
Oh, and last thing I can think of is, if you're planning to stay at Hagey's but have a plan B or meet some nice burners on the plane who are renting a car, or have some other way to bypass Hagey's, I think you should try to do so.
