If you were attempting a thru-hike of the Appalachian Trail, starting roughly now (being mid to late March) and going northbound, how many sleeping bags and of what types would you need, assuming cost is not an option?
So a little background. I've talked to a number of people who have thru-hiked northbound on the AT, and have heard about the various sleeping conditions. Assuming a pace of about 5 months, would different bags be needed for March in GA, June in VA, August in VT, etc? Obviously I don't plan on carrying more than one bag at a time, but if need be bags could be mailed to spots on the trail at certain dates.
Minimizing weight is always #1 on the priority list, but staying warm up north in the later months would be #2. I've mostly lived in the VA region of the AT, so I am used to backpacking with a very lightweight sleeping bag in summer months.
Also, I'm hoping for this to be information given a usual year, not necessarily the spring going on right now in 2012. I am planning to thru-hike the AT in 2013.
