Several of us are thinking of hiking the 100-Mile Wilderness (south to north), then continuing to push on to Katahdin. Right now, we're targeting the last half of September 2015.

Any thoughts on that time of year? We're hoping to find a window between the black flies/mosquitos and cold weather/snow.

Also, we're guessing that we should plan two weeks on the outside for that trip.

Any advice -- general or specific to the questions above -- much appreciated!
