Interesting article in The Guardian about open-carry laws in Texas:

Open carry of handguns in Texas: fear for some but 'everybody else is packing'

I have to say I would view someone openly carrying a gun very dimly. It's an act of aggression and designed to intimidate others, pure and simple. I guess it's designed to stop you arguing with the ape carrying the gun in case he/she looses his/hers temper and pops a cap in yo ass. Nice.
