Whoa, Chris. Don't make assumptions about people's abilities. You have no clue as to the extent of our experience, preparation, or fitness levels. If you had done your Canyon research properly, you would know that going rim-to-rim on a non-summer day is quite common and uneventful for experienced, prepared, and fit people. That you would think only "fully staffed crews" can do the hike shows that you are a bit out of the loop on this issue.

Try this link, for example http://www.toddshikingguide.com/Hikes/Arizona/GrandCanyon/Canyon2.htm BTW, I have been in contact with the author of this report and have become familiar with his background & abilities in relation to the hike he did.

The "Aron Ralston" comment was uncalled for, especially in this community.
