My piece about Hummers a few days ago reminded me about the rich idiots who buy the civilian versions. That reminded me of an anti-hummer banner above.
A few years ago in California, people realized that CalTrans was particularly lax about removing political banners affixed to freeway overpasses. So those with a message to get out started making banners and plastering them all over the freeways knowing that the captive market crawling through rush-hour at 3mph would having nothing better to do than stare at the messages. (Well, aside from those reading the paper, typing on laptops, or watching videos. Yes, I've seen drivers do all of those things and worse. Don't get me started on idiots who pair fellatio and driving at 75mph.)
And, of course, don't forget to read some pithy commentary about civilian hummers and the losers who drive those 10mpg gas-guzzling monstrosities.
