You can currently drive in with your own vehicle but will still have to pay the Ranger man (or lady) at the gate. Flows are getting skinny and it has become more difficult to fool the fish in the shallow riffles. The pocket water is limited and you will see the fish begin to move into the larger pools as the air begins to cool and flows continue to drop. Dry dropper bead head rigs make sense for this kind of condition. Do NOT leave any thing that even resembles food in your car while you are away, the bears are on the prowl everywhere.
