I'm with OM on this one. If I am out the backcountry with my wife, we avoid situations that might require a rope. That's using the best single tool we carry with us: our judgement.

But I have rock climbed, and enjoyed it. And I can imagine doing a trip that migth combine both backcountry and rock climbing. That trip would not include my wife, by her choice.

And right now, I'd rather spend time with her than with a rope!
