After a long battle, in January 2015 the Federal Appeals Court ruled that allowing for an Eruv was not a violation of the First Ammendment.
Rabbi Shlomo Francis and Rabbi Yonason Glenner visited Miami and gave their fascinating Powerpoint Presentation teaching all about the different areas of the Eruv. They gave five Shiurim in different Jewish communities in the greater Miami area, and they were well attended. The communities included Miami Beach, North Miami Beach, Boca Raton, East Boca Raton, and Hollywood.
After 7 years of legal controversy, in January 2006, the Tenafly Eruv Association was approved to erect an Eruv.
