The ironic thing about this is that OCDO got the billboard space from ClearChannel, the same guys that donated 30 billboards to an anti-gun group in Philadelphia.
OCDO is pushing for this image to be distributed around the intarwebz viral-style, so if you're a friend of open handgun carry in Texas, this image is public domain; post it wherever you think it'll make a difference. OCDO is also accepting donations for the next wave of taxicab advertisements on Austin cabs. Spam over, we now return you to your regular CHL threads.
