MMULLINS,
I have a brother up in Fairbanks, Alaska who swears by Wiggly's bags. They seem overkill for Texas though. Saturday night here was pretty much as cold as it gets. Last winter we had frost three times and that was a big deal. <img src="/images/graemlins/shocked.gif" alt="" />
I swung by Academy Sports (local Outdoorsy store chain) over lunch and looked at bags. The problem was they were all too short. I'm 6'5", and 72" mummy bag just doesn't fit. The main reason I bought the bag I have now was that it's 90" long (outside measurement, inside length maybe 86"). I shove my clothes down in the bottom of it so they'll be somewhat warm in the morning.
What I'd really like to do is find a liner or cover for this bag to up it's warmth even if this involves sewing something myself (well, actually DW would do the sewing, I would supply the dinner at a nice resturant as payment <img src="/images/graemlins/wink.gif" alt="" />).
