I'm planning to try the Rim2Rim2Rim route that Andrew Skurka wrote about earlier this year on Sunday, starting at the S. Kaibab trail around 5AM. Would love to have company if anyone is in the area! I'm planning to take about 14-16 hours to complete this, based on the challenging amount of vertical (21k feet. Wow!)
Please email me (watkinsgibbs*at*yahoo.com) or call me 415.902.9182, as I don't check the forums all that often.
