Moab, Utah, Arches National Park. A hard rain/lighting storm came in a dropped the temperature in Arches National Park 54 degrees F. It was hailing. I was in my t-shirt and shorts while it was hailing. I was fortunate to get a break. My goal was a lighting strike above the rocks but I got something better. 30 min before everyone left except me and a nice German fellow… I told him to stay cause i think a rainbow will appear. He thanked me cause he would have left without seeing the site.
