Wave Vidmar is currently trekking to the North Pole, solo and unsupported (no dogs, no airdrops, etc.). He will be only the third person to complete this feat (first American). I just want to promote his site,

jounal entries can be found under the expedition section, then "Wave's Logbook."
i check on it daily.
