This guy sounds like a real...well, not to revive a thread...idiot, 
Paddler.  But what he said about circulating air was right, sort of. 
If the air is still and the skies are clear, the coldest air will 
settle in the low spots.  If the air is moving, it is mixed,and the 
coldest air doesn't "settle out" in the valleys.




Also: Victor Hoyt said:"You should be aware that the Green Mountain 
Club discourages hiking on the LT during mud season."

LT mud season--Yup, the mud season is  after things start to thaw, 
'till about May 30th.  Sections of  Camels Hump and Mansfield are 
closed 'till then.  the real problem is the top layer of ground gets 
thawed while underneath it is still frozen.  The thawed mud just 
slides right off.  Very bad erosion.
