Just 3 volunteers (1 Briton, 1 American and 1 Japanese) collected 40 bags of trash. We cheated a bit with about 5 bags collected the day before on the route walk through and then another 8 bags or so from a mini-garbage dump that a homeless guy living under the bridge left. Anyway, a nice haul for just three people, and beautiful weather for January. Then, dinner at Sazeria afterwards.
