I don't like to be cold, but I sweat like the dickens once I get going. I'll have the zip-off leg pants, so I'm good there, but what should I wear on the upper half? Assuming an 8am start (is that early enough to avoid parking lot mayhem?) would my packable rain jacket be enough? Or should I add a long sleeve thermal shirt? fleece pull-over? parka and (fake) rabbit fur gloves? or neither and just hike in a bathing suit? :)
Coming from Dallas, I'm concerned that the low humidity and 40-50 degree morning weather will feel really cold. But then once it warms up at 10am or so, I don't want to feel like a pack animal hauling half my closet up the trail.
