Zip lines and old people

Sitting in restaurant with S, outside I see a Western view--ruddy orange rocks which block my view into a very deep canyon.  I can see the other side of the canyon rising above them in the distance.  I see people jumping from the top of the far canyon wall, just small dark silhouettes at this distance.  S is talking and I interrupt to show her the jumpers, and count ten of them.  Then I notice that there are wires strung across the canyon, several of them, and that people are using them as jump lines.  They speed across the air suspended below a line, zooming into close up view before jumping off onto the near cliff face.  (I recently watched a video about S. American people commuting across a valley using these zip lines.)  Absurdly, a Volkswagon minibus glides across the wires as well.
Scene shifts to edge of canyon.  I'm in line behind others, particularly an elderly couple, as we wait to descend the cliff face sitting in inner tubes.  My attention is focused on the faces and near-naked bodies of this couple.  They are oddly beautiful, with translucent skin over lean bodies.  Their cheekbones are prominent, and they are happy.  I wake before we descend.  Very positive encounter.
