. Three landowners in Washington County will be honored today for their efforts to protect open spaces in the Twin Cities area. They will receive awards from the McKnight Foundation, which wants to raise awareness about threats to natural areas. One of the awards will go to David Hartwell, on behalf of his family. Hartwell is the grandson of Charlie Bell and the president of Belwin, a nonprofit organization set up by the Bell family to protect open space in the Afton area. Hartwell says it all started when his grandparents bought a weekend retreat near Afton.
