"Well, yes," I'd answer. "I do this most every year."
"I go there with my dad. We hike together."
"Don't you and your dad want to do something different one of these years?"
"Well, no. It wouldn't be the same. Rim-to-rim is the tradition."
Now it's been a few years since I've been back, at least to the depths of the canyon. In 2013, a government shutdown prevented us from entering the national park. In 2014, I'd torn a ligament in my knee and couldn't hike, so instead did the drive-around with my mom, who joins every year to support the crossing. This year, my dad proposed a rim-to-rim-to-rim, hiking north to south one day and then back, south to north, the next. I suppose one might argue that a true R2R2R must be done in a day, so this is more like a back-to-back R2R. I'd still never completed the out-and-back, and was excited to see the canyon from both directions in the same weekend.
