Neighbor Sergey Smirnov wrote this recently on the Beacon Hill mailing list:
This past Sunday, in honor of Earth Day, we organized a litter clean up in North Beacon Hill. Twelve neighbors gathered together to make the neighborhood a cleaner place for all and collected over 60 pounds of trash. We focused our efforts on the area around the Beacon Hill Playground, gathering trash from South 12th, 13th and 14th Avenues from South Massachusetts to South Hill and the adjacent alleys. Plus — we all had a blast! We hope to make this a quarterly clean up — let me know if you would like to join us next time!
