I've noticed something about boxcars. Very often, they have elaborate graffiti spray painted on them. It makes me wonder where they have been.
A railroad track runs very close to our office, so I always see the trains going by. The graffiti on some of the boxcars is truly intricate. It makes me wish some of the young people who spent so much time creating that graffiti could go to art school and learn to use their artistic gifts in a way that might be profitable. It's a shame they have that talent, and probably no way to benefit from it, except for spraying graffiti on any flat surface.
