Just my group there.. Someone drove through around 10pm (think it was a ranger). We only saw head lights in the distance once.. It was awesome! I need to learn the roads around there so I know what is where. I will try the other way to the hot springs (the right before the ranch then all lefts) next time I go. I loved the hot springs, well more the nice just warm water in the creek next to the hot springs. I need to bring a float next time I come down. And the hike is not as had as everyone has told me..
