I realize this is late notice, but I have a free ticket to hear Ed Viesturs at the National Geographic in Washington DC, Tonight (April 16th) this is a sold out event. Let me know if you want it and I can meet you in the lobby before it starts.
Of all the slide shows of hardcore alpinists I've seen, Ed is by far the most polished speaker. I had a GF whose boss had season tickets to Benaroya Hall in Seattle (typically operas and such). He gave her the Ed Viestures tickets and she brought me along. The audience was decidedly non dirt bag climbers (mostly rich folks used to listening to high brow music and lectures) and Ed had the whole audience eating out his hand. He did a question and answer section at the end with audience members submitting question on 3 x 5 cards.
Question: How do you go do the bathroom on Everest? Answer: Quickly. Because its cold.
