The one time I was near the gate when the bus went by (after the era hikers got a ride), the drive stopped, turned off the bus, removed his seat belt, got out of the bus, opened the gate, went back in the bus, put on his seat belt, started the bus, drove 50 feet, stopped the bus, took off his seat belt, got out of the bus, shut the gate, got back in the bus, put on his seat belt, started the bus, and continued driving. Apparently, either no one in the bus was willing to jump out and operate the gate, or it was forbidden.
I did get to drive all the way to the end of the road once, but that's another story.
