So, the first night that I stayed in the Toulumne area I parked the RV off the road up by a trail head, but around 9:30pm I got a knock from the Park Rangers, they told me I couldn't camp there, and kicked me out of the park. I drove right outside the Yosemite Park boundary and camped there. The next morning I drove back into the Park really early (so I wouldn't have to pay the entrance fee). Driving back in, I stumbled on this lake just off of the hwy. The sunrise produced some good light.
