Free Girl
Yesterday on my way home from work, I pulled behind this truck on the off-ramp. (Are you allowed to drive with your small child in the bed of your truck, ever? Not to mention on the freeway.)

She waved and then held up this sign: free. She held up the sign with great determination the entire time I followed the truck. What was free? The young girl? The truck? If I wasn't so tired I could probably come up with something clever.
