This Everest expedition is on the North Side of Everest with the Russian Adventure Team.  I'll definitely be using Oxygen and there'll be Sherpa support as well.  The time line of the expedition is as follows - Meet in Kathmandu on the 8th, drive to the North Side Base Camp a day or two later and arrive around April 15th.  From there we'll be acclimatizing and hope to go for the summit in late May.  Visit SeracFilms.com for some pictures of getting to the North Side and what it's like there.
