Mark Trail comic: Don't litter
I see an incredible amount of litter in DC. When I go to other places, I don't see near as much (usually). When I see stuff in the gutter, I imagine it ending up in the Anacostia and Potomac Rivers...
Take a free ride on the Northwest Branch of the Anacostia River sometime from the Bladensburg Waterfront Park in Bladensburg, Maryland, and you will see a lot of trash up against the banks of the river.
Today's Mark Trail comic strip addresses litter.
