The Wynnewood area has a eruv under the supervision of Rabbi Gross from Congregation Beth Hamedrosh. It is checked weekly by community volunteers. Please contact the Beth Hamedrosh if you are interested in serving as a volunteer.
The goal of the Eruv was the desire to provide a service to the broader community. The eruv is an integral part of Shabbos observance and a service that people use to come together as a community.
