We have other plans that weekend and won't be able to make it. Too bad, I would have liked the chance to redeem myself on the road that earned me the moniker Magellan. Oh well.
The campground proper is at 41° 21’ 36” N 119° 13’ 21” W. If you look at this on Google Earth, you can see another sight almost due south 1/2 mile. I recall a fairly large group being in that spot, so it may be an option. However, to get to that site you have to go east to the main road and then west again on the road that goes a little south. Also, the roads are hard to see because they are hidden in the sage so it can be difficult to find them.
Be sure to check out the free cabin (which has a decent vault toilet next to it btw) due east of the campground about 1 1/3 miles, too. Most guests leave a message on the walls which can lead to some interesting reading.
Have fun.
