Positive contact!

You know when you are in a van, almost at the top of a very high mountain, on a two-way single track road, when the driver realizes that the "empty tank" flag is on, and has to turn around at a curb where nobody coming or going could see the idling van, and almost falls off the cliff in turning around, and then decides to save gas while coasting downhill on neutral at SIXTY MILES AN HOUR when the terrain is rumbly, and you realize that every time you look at the driver he is admiring the adjoining mountains and cliffs and not the road, and you are trying to be too polite to say anything, because he is your boyfriend's dad and because going 60 is good for fuel efficiency, and you realize you're about to barf, and you consider saying something, but then realize that it's better to barf than to be thrown off a cliff or run out of gas in a place where no cell phones work and no one knows where you are, so you take a plastic grocery bag and place it right next to you, just in case?

Yeah, that's when you know you shouldn't have gone for "a hike" that day.
