I returned to climb Mt. Everest and stood on the summit on May 21, 2011.You can read about my climb over the internet on my Blog at www.alanarnette.com/blog.
This was to raise awareness and research funds for Alzheimer's Disease and 100% of all donations go to Alzheimer's. This was part of climbing the 7 Summits - the highest mountain on each continent.
