My wife and I have lived in Reston, in the townhouse I bought in 1976. It's walking distance to the grocery store and I walked occasionally during my working years, more often now I'm retired. The neighborhood has had its problems over the years, as two of the section 8 subsidized housing projects in Reston were a ways down the street. ("Were" not because they've been destroyed, but Fairfax county has converted them somehow.)
Anyhow, with regard to trash on the ground, there are three categories of people:
- Droppers, including people in cars, who drop trash
- Walkers, including people in cars, who just pass by.
- Pickers, excluding people in cars, who pick up trash.
