There are national brands of flour available all over that are Yoshon year round. No need to stock up like that.
Good old Joe went on a rant in which he describes the greater quantity of yiddishkeit on the East Coast. Not sure he proved anything about the quality. Where I live there are also places with 3 shuls on a block. Not so many such places, but they are there. We fill our shuls, we fill our yeshivos. Brooklyn has more, because they have more people. But that is quantity, not quality.
We have Hatzala, Chaveirim, Bikur Cholim, a Chessed Fund Warehouse that is unmatched anywhere in the world including Lakewood. And we don’t antagonize the police when they try to give a parking ticket, so they like us, and respond when we need, so there’s no need for Shomrim. And a Chevra Kadisha that does much of what misaskim does.
We don’t have hundreds of gemachs, but we probably have dozens.
I’m not finding children of local people moving to Brooklyn any more that are moving from there to here. Lakewood is different, because they go there to learn.
