The real tour guide let me bring my flashlight into the cave. I had so much fun. When she turned off all the lights so we could see how dark the cave was I turned on my flashlight - I was prepared.
The Homestead Crater in Midway, Utah. It's a natural hot springs cavern inside a rock dome. You get into it through a tunnel. I brought my flashlight and pretended to be a tour guide. The water is 96 degrees. The pool is 60' wide and 65' deep. We've had alot of rain here recently and we had fun in the parking lot, too. YES, life is good.
