What kind of daily mileage does someone expect to make in that in the Whites or southern Maine, especially when they get to the sustained 50+ degree inclines? Again, I just think there is an air of unreality based on very little information here. I suggest anyone inclined to leave SOBO in what is just about winter should get more info before committing to doing it.
P.S. I will add that I was in Baxter Park from what, October 12-15, 2006 . Katahdin (little different elevation from some of the Presidentials, and lower than Mt. Washington by about a thousand feet) had already had at least one Class IV day before I got there. There was snow and ice in the shade that 2 sunny days in a row had not melted. I can only guess what it would have been like a month later. This is what southernpine is intending to go into. While not like the 3 guys that got themselves killed on Mt. Hood (?) last winter, the 4 Quebecers that started up the Huntingdon Ravine trail late afternoon in street clothes, etc., it still smacks to me of poor judgement/information for someone not already an expert on that activity to do.
There are people on this site who could do this thing, albeit still with some challenges. I'm not yet inclined to think the original poster is one of them.
