Tolley Praises Local Farms

MANCHESTER (June 2)-Local horticulture expert Cassandra Tolley is scheduled to deliver a lecture Friday night at the Burton Auditorium in Manchester. The owner of Green Ridge Farm in nearby Windham County, Ms. Tolley will discuss the importance of supporting and promoting local farmers. A strong advocate for small-scale farmers and a small-scale farmer herself, Ms. Tolley has traveled extensively over the past few years to deliver her message of "eating locally." "If we make an effort to source our ingredients locally, we not only sustain and assist the local economy, we also encourage variety in the marketplace," says Ms. Tolley. "And that is beneficial to consumers."

"Everyone should spend their weekends browsing the regional farmers' markets," she adds. "It's the best place to get your groceries during the summer." Friday night's lecture begins at 7 P.M. It is free, but seating is limited. Please arrive early. To view a comprehensive listing of statewide summer farmers' markets, visit www.vermontfarmersmarkets.org.
