Mods, this post is the second to the long post.
Well,within twenty years after the above was published, an eruv was put up in Flatbush and people were saying that it was with Rav Moshe’s agreement. Rav Moshe had given his agreement to Kew Garden Hills on their eruv. A quick look at a map of the area would show none of the issues that Rav Moshe discussed. Also Rav Moshe put out a letter with four clear conditions.
1. All the Local Rabbonim agreed. (This has happened almost nowhere else.)
2. Excluded the highway.
3. It is difficult for it to become ruined.
4. there is a designated person to check it every Friday.
The letter ends of that it is not comparable to why there is no eruv in the city.
Somehow, there seemed to be an honest question of what Rav Moshe really held. Rabbonim came talk to him, and he was surprised that they weren’t familiar with his printed teshuva. Sounds familiar?
