One time when Craig (Groundlooper) and I where flying around in my Savannah, landing on all the roads and lake beds in the Alvord area. I landed on one that I thought was totally dry, as was everything else.... holy shit was I wrong, had I applied any more brakes or any less power we would have been stuck for sure! I had to keep full power in to barely taxi to the side where luckily there was enough room and somewhat hard enough crap where keeping it in full power I was barely able to get it up to 20mph to get off the ground. Very close call, I feel lucky we didn't stick in and flip over or something worse than what happened. So always be careful and land as close to the edge of the dry lake beds as possible. A proper examination of the area on google earth might have made me think twice about landing there as it listed on there as "Lower Borax Reservoir".
On another note they are now charging for Alvord Hot Springs, as the new owners recently took control and built a house right there as well. I would suggest to anyone wanting a more private hot spring experience check out Bog Hot Springs, its 37nm from the south tip of the Alvord in Nevada, and you can stop by Fields Station or Denio Junction on the way. There is a long straight flat road you could land most anything, though everyone might not want to taxi all the way to the hot springs. Willow Creek Hot Springs is cool and only 16nm frin the Alvord, but the road is not quite as kind, though there is a straighter wide road about a mile or so away that is a lot smoother...
Hope you had or will have fun!
