If that's really how you want to spend your money, what the billboard owner wants on their signs, and legal content thensure why couldn't you do that? We can't be censoring anything we find offensive, or even worse anything we think might offend someone else. Trying to draw a line for what is legally banned content is enough of a gray area, there's absolutely no way to draw a line when the metric is what may offend someone.
