Day 12.0: What's the superlative of Grand?

Perhaps Grandissimo would have better described the Grand Canyon. We hiked the Bright Angel Trail on the So. rim...3-4 mile round trip descending from about 7,500 ft to about 5,000 feet and up again. We did encounter mule shit on the trail, but as Virginia says, at least you can smell it before you see it (to avoid it). Later we hiked the Rim Trail for another few hours, and also hopped on and off the shuttle buses between vista points. Altogether, we covered about 40 miles of the So. Rim yesterday afternoon and today. More shots to follow.
