It appears that R.A. Dickey, along with Kevin Slowey and Dave Racaniello defeated Mount Kilimanjro, reaching the Uhuru Peak, the highest point of the mountain. You can read about the last trek up the mountain here: http://bats.blogs.nytimes.com/2012/01/14/reaching-the-summit-of-kilimanjaro/?partner=rss&emc=rss
Of course, he still has to get down the mountain. I suppose finding a cardboard box and sliding down is out of the question. It would probably be a killer ride, if you could avoid the cliffs that could make that last descent too much of a killer.
Congratulations to the trio.
