TomD,

Sorry to hear about your HAPE episodes. Met some young Swiss climbers on a boat on Lake Titicaca that had just returned from Mt. Ilimane. They got really sick and vowed to never go that high again, 19,000 feet. You are correct to caution people about the dangers of high elevation.

Most people who are healthy can probably do okay at elevations below 13,000 feet. What other advice can you give those that want to go higher?
