Pooch,
I wouldn't make any special arrangements, unless hanging or leaning it against the wall,turns out to be unsatisfactory. I live in Alabama and the warm weather and humidity works fine.I would guess Texas would be similar.Too much water vapor can result in streaking.The thing about rust bluing is if you make a mistake,you can redo it.Just don't let it go overnight without boiling(you can card it later once the rust is "killed"), otherwise it can pit.
