I am planning a SOBO thru hike starting in june/july of 2013 and i have read alot about "the whites", I was wondering what states/parks these mountains are actually in, and when would be the best time to ship home my cold weather gear (location and/or time of year). Also I am planning on using a 30 degree bag with a liner will this be warm enough? and lastley shoes..... should i go lightweight or get waterproof hiking shoes/boots?
