We were south of you in Joshua Tree NP. The rain came down for 16-18 hours, with winds of 15-65 MPH.
The previous two days we had explored the area, so we just hunkered down and listened to the rain on the roof. We did feel bad about the tenters in the park, but 45 years ago, that was us.
It is a shame about Scott's castle. We were there in March of last year and went on the tour. Fascinating story about one of the greatest con-men of all times. If you get the chance after they re-open, go take the tour.
