A gondola ride along a river

I'm in a stadium carved out of rock with my family. We're under a ceiling of rock - there is no event going on, but jumbo television screens are showing a sports ceremony similar to the Olympics opening or closing ceremony. Suddenly, a security guard to the side of our section starts firing into the crowd. Nobody panics, not even everybody takes notice and those who do don't see it as unusual that the crowd is being fired upon. I leave.

I'm driving down a steep hill in an unfamiliar car. The brakes don't work well and I'm unable to make a turn at the bottom of the hill. I crash through a guard rail into overgrowth. I've had a few beers and don't want to call a tow truck or have the police find out. I fold up the car like a tent and carry it through the woods by the road. The road runs parallel to a river - the area between the road and river is a public park. I walk over a large hill of gravel and see an area of the park beyond a fence which requires a ticket to access. I crawl under the fence, nobody notices.

There is a roller coaster/train/gondola type ride running parallel to the river. There are grapples on cables passing by - passengers/riders are attached to most. I take a place on a line and immediately realize I've gotten on a line intended for small children. I have t6o switch to the adult size quickly as the line is approaching a narrow vertical chute - the child chute isn't large enough for me.

I get off at the end of the line and meet a friend walking toward me on a path through the woods. The dream shifts - my friend and I are the engineers responsible for keeping the ride in working order. My friend wants a cigarette - they are sold in packs of four at concession stands along the route. They're very poor quality and my friend complains. We grumble that if we quit our jobs, the owners would have to pay a lot of money to get someone who could figure out how the contraption works.
