I will be travelling to Israel in a few weeks, and expect to be in Jerusalem for Shabbos. I've been trying to find out about the eiruv in Jerusalem (I've heard that there are two, one certified by the Badat"z and one by the Rabbinate):
Does anyone know the boundaries of the(se) eiruv(in)? Can one carry across Bar Ilan using the eiruv? And (please, no politics, just a straightforward answer!) who certifies which eiruv?
