The weather turned when I was in the cavern. When I came out the road out of the park was closed. OK don't panic I am sure something is done in this case. I went to the restaurant and watched the weather. Within a half hour the road was open but thunderstorms were likely. Blue sky ahead I just needed to get there. The weather warning was buzzing announcing counties not to go in, of course I don't know what county I am in and Siri was not available plus she keeps calling me Kia. I just drove towards blue sky and watched the storm and lighting in my rear view mirror trying to gage if I could safely move fast enough to avoid the storm. Of course happy ending I did.
