You'll probably only need an UQ from Dec - Feb in Houston, where it's over 70 degrees most of the rest of the year. But you'll need a BIG tarp to keep all that rain off, and I'd suggest the MacCat Deluxe. I'm in Brenham and just learning. Wish I'd known about Blackbirds before I invested in a couple of HHs... (one Exped, then a ligher BULA) Of course, most of my hammocking won't be here, it's on the Appalachian Trail.
Let me know if you'd be interested in a outing to Hunstville State Park - trying to get some guys together (or some other park)
