Pick up your ground

I heard from a number of Facebook friends that they regularly carry bags with them on walks to pick-up garbage when they inevitably find it along the way. One person suggested we start a movement to encourage others to do likewise.  We can call it "Pick up your Ground".  The participants would be encouraged to "Conceal and Carry" trash bags when they are out and about.  Want to join the movement?  No membership fees required, just do it.
