LOL

The beginner river I use for training has one, count 'em, one rapid in
the first day's section. Total drop of the rapid is maybe 2 feet. Maybe
less, and it's a straight shot down the center of the river. You have
to do a number of things wrong to flip in it, and so far, only one
boat, a tandem crewed by a married couple, has managed that feat. They
self-rescued and i saw them in the pool below the drop, talking
animatedly. Seeing this as a good instructional opportunity, a
"teachable moment" as we say in the biz, I paddled over and started my
spiel "Let's talk about why you..." The woman turned away from her
partner and fixed me with a hard glare. "If you DON'T mind, we're still
arguing."

No info as to whether they are still paddling the same boat, or even
still paddling.

However, I do know several very accomplished tandem teams who are still
very happily coupled.
