OK, so we rescheduled our Art Loeb hike due to the huge amounts of rain, so now we are looking at November time from. Any advice on what temps are typically seen up on the trail in mid November? Asheville is showing historical lows in the mid 30's, so I am expecting maybe 20's up in the higher elevations maybe? Anyone know for sure? I am trying to decide about insulation. My current setup has had me warm down to around 30, so I am wondering if I need to make any changes.
