I bet you could get 4 seasons out of it in the south, don't you think? I don't know much about sleeping bags, though.

It's a good idea to think of the temperature rating of sleeping bags as "survivable" rather than "comfortable."

I camp year round in CA. I use a 20 degree bag for late spring/summer/early fall and a 0 degree bag for the rest.

In the south maybe, but if the temp gets anywhere near 30F then no.

I do a fair bit of camping and I use a 0 degree down quilt from September through May where I live, rest of the year a 20 degree down quilt or bag.
