It was my off-beat sense of humor. I was referring to the canyon itself as the big erosion problem. Tongue was firmly in cheek at the time. You guys have a great trip, and I guess by the time you get home we'll be on our way to Alaska (where, by the way, they do have a big erosion problem--the road we'll be taking was washed out in two places a week ago. We've been assured it's fixed now).
It's never too late to have a happy childhood!
