My nephew Doug climbed Mt. Moosilauke today, which is the last of his 48 4000 footers. A lot of his climbs were in winter - always an extra burden. For those from the Rockies who sneer at such small mountains, I understand that the rockiness and slippery footing make the New England mountains harder than one would think. If you want to tell me I'm wrong, come try 'em.
So, congratulations. He's made a big dent in the Hundred Highest already, which is his next project.
