Somebody feels compelled to let people know Millennium Park used to be a Boston city dump

On her morning walks through Millennium Park in West Roxbury, Mary Ellen usually looks for birds and other interesting creatures, but of late, she's noticed that somebody's been digging up manmade stuff from the mud along the Charles River edge of what was the Gardner Street Landfill until the 1990s.

Park oldtimers, of course, know about the remains of two friezes along the river.
