Yes, open carry should definitely be a compliment to concealed carry. Texas could also use a few others changes with regards to firearms.
I just moved to Texas after living in Colorado and Pennsylvania. In both states, I never once worried about carrying because there really aren't any places off-limits (except the standard courthouses and schools), signs carry no legal weight, and printing isn't an issue because open carry is perfectly legal. However, here in Texas, I'm constantly looking out for 30.06 and 51% signs, and always conscience of printing. It actually takes a lot of effort to stay legal, which I don't think is very fair.
