By the way...
We had arranged with some other people to meet on Saturday and ride Poison Spider Mesa. We got into Moab late and was unable to hook up.
Since we have learned that they did Hell's Revenge trail later that day and had some problems with water, sumps and flops.
One of the guys drove into a sump but found it was too deep. Yes, his engine seized with the water. The entry was deep.
One of the other guys flopped on tip-over challenge.
For them it was not a good weekend...
