BOSTON—Despite having never before given the topic a moment's thought, maintenance mechanic Ron Krueger, 46, aggressively defended his home state of Pennsylvania's license plate design Monday after a coworker's negative comment. "The horizontal bands of blue, white, and yellow are not only bold, but they're the perfect color combination," Krueger said in defense of the piece of aluminum. "Also, it's ridiculous for you to not like the font. Check out the stupid frilly letters on your license plate; they look terrible. State names should always be in caps. Always." Krueger was later surprised at how angry he became when a coworker complained that it took a long time to drive across Pennsylvania.
