This picture was captured from a camera mounted on the handlebars of my bike, approximately three and a half feet off the ground, as I was dropping my kid off at soccer practice.
I take a lot of photos of these trucks, trying to illustrate just how menacing and out of place they are. I get a lot of grief for it too, but the thing is, when I encounter one of these monsters while walking or biking with my kid, it's almost always in a place that kids should expect to feel safe: on a neighborhood street. Next to a playground. At the bus stop. In the school drop-off line. In a crosswalk. At the soccer park. In a bike lane. On a sidewalk.
It's not ok.
