kirk bower, steve martin, dpaif boardened and jessie.reat to see all of you. >> thank you fredricka. >> let me begin with you, kirk. you were unstoppable. one adventure after the next. so all of you make up the first team of amputees, trying to scale denali and alaska together. why and what's going to be the greatest challenge about this peak? >> well, actually fredricka, there's a number of challenges that we're training for. one of them, of course, the prothesis themselves. they're made of plastic and metal. very, very cold weather, the carbon fiber, may crack. it does a lot of pressure on our residual limb. exsergs wise, steve martin, they'll spend as much as 200% more energy climbing this mountain as nondisabled person. so we actually have to be in better shape than the regular climb toers try to meet this challenge. so there's a lot of challenges, but we think that we've prepared for it and ready to go. >> you know, kirk, this is not a first for you guys doing these incredibly climbs. you led a team in 2010 of mt. kill man jar row i
