A. A Community Rav
- Must take responsibility for the community Eruv in all circumstances.
- Must train and supervise the weekly Eruv inspector to insure a valid Eruv.
- Must know Hilchot Eruvin thoroughly.
- Must know exactly how the Eruv works (especially the most challenging portions of an Eruv).
- He should scrupulously inspect the Eruv at least once a year, in some situations on foot.
- He must know that the Eruv inspector is worthy of the job (Netiruta D’dahava vs. Netiruta D’Kaspa) both in knowledge and Yirat Shamayim.
B. Styles of Eruvin – the advantages and disadvantages of each.
- Park Slope – simple to maintain but expensive.
- San Francisco – four Lechis did the trick. Square, Tachuv and much research to find the already existing Eruv (note the challenges with the Sechirat Reshut and tip of donning a baseball hat when wearing an Eruv).
- Rav Moshe Feinstein, Rav Heinemann (and Rav Eider) and Rav Hershel Schachter – their different styles and requirements (both L’Kula and L’Chumra).
- Flatlands – inexpensive but complex and labor intensive.
- Oakland – Pi Tikrah, Chritzin etc.
- Teaneck, West Orange, Scarsdale and Englewood – Highways passing above or below the Eruv.
- 1. Simplicity – Whenever possible Lechis should extend entirely to the wire (avoids problems of alignment issues and it also helps you keep track of the Eruv).
- Community education and awareness (Roslyn Heights story).
- Eruv Ethics – permission (Rav Soloveitchik story).
- Effectively relating to the broader community (not creating nuisances etc.).
- Karpeif Management (Bnei Brak, Teaneck, Connecticut stories).
- Accommodate Chumrot if possible (Flatlands and E. 36 Street story).
D. It’s an Hour Before Shabbat and the Eruv is “down” !!!!
- Potential Kullot: Eye sight alignment, Gud Asik, tapered poles, stop sign Kula, change of direction tolerance etc.
- Be prepared with Lechis (and a shovel in certain communities) and know Ten Tephachim and ten Amot measurements based on your foot and hip.
- Know in advance the Eruv Posek’s stance regarding these matters.
E. The Politics (or Human Relationships) of Eruvin – Potential Challenges from:
- Those outside the observant community.
- Being politically savvy with government officials (similarity to dealing with Koresh and Daryavesh etc.in Sefer Ezra and Nechemiah.
- Those Jews who do not want to want to rely on the Eruv.
- Which Rav to choose (or which Chumrot to choose – note that Chumrot often involve extra cost both in terms of construction and inspection time).
- Call the Eruv down once a year (or maybe not).
