Half-Hidden Graffiti

 Last week, I walked along a paved trail that goes under a busy street. Graffiti artists have left their tags on the more sheltered part of an overpass. Crisp, regimented black and white letters contrast with ballooning nicknames and alien-like figures in bright colors. I saw just a sliver as I walked past. In a world of sand and concrete, this fleeting outburst of color and creativity was a welcome surprise.
