Under normal seasonal closures, the Tioga Road is gated just above Crane's Flat. It would be great to bicycle up the road, but alas, the fine makes it not worth the fun.

Now Redwood National Park would be near impossible to close. One dead-end road is gated, but there are no other gates. And fortunately there are the surrounding State Redwoods Parks with access (but who knows what the State budget mess will result in.)
