I live in NC and have spent considerable time in the higher mountains here in March and there's no way I go there in March at 5000 + feet with a 32 degree bag, nor a 20 degree bag for that matter. I've seen it around 10 degrees to even 0 degrees here that time of year all too often. I carry a 0 bag in the mts of NC throughout the winters. You can always leave it partly unzipped for the 20 to 30 degree nights. The weather here is just too inconsistent, but we surely can't carry 3 different bags to match the weather here like we really need to. It can be anything from 0 to 50 or 60 degrees.
