Gary - very good description and advice. We followed a lot of this, including eating 4000+ calories and drinking a lot of water.
So true on the last stretch. The mountain looks so close and it looks flat (it still is 800+ feet climbing!) There were people at the intersection with the JMT that said "it is only 1.9 miles, let's drop our day packs and finish without supplies!!!"
- those guys never made it to the summit. As a matter of fact, 90% of the people that we started with never made it. Unfortunately there are a lot of non-hikers thinking they can bag this peak because they saw someone grinning in a selfie up top on instagram.
