Amongst all the straight-up tagging, cities are home to inspirational and thought-provoking graffiti. I always wonder what the person who did it looks like and what is happening in their life. Here are two messages I recently saw in San Diego that I can get behind. I picture someone just fed up with America’s obesity epidemic and another individual shaking their head saying “It’s 2010. Get over differences in the color of our skin.” Seen anything lately in your city? Do share!
