Oprah and here crew were in Yosemite this past week. Lower pines was the unfortunate site for filming some of their segments. Lights and generators running until late in the night. It was so annoying and should have been done elsewhere. No one even slept in the campsite. The park was very cooperative with them, I would have gotten fined to death if I did even a little of what they were doing.
The thing that bothered me the most was the fleet of cars speeding through the campgrounds, not cool at all.
