I read them.
ICOT: one point regarding the Belt Pkwy: I was told that R’ Moshe held that people in cars don’t count towards the 600,000, as a car is considered an ohel, and the person is considered indoors. On the Belt, you can’t count 1 in 5 as being outdoors. R’ Ovadiah Yosef disagrees with him on this, and says people in cars do count towards the 600,000.
Just to note, I am against the eruv, I’m just pointing something out.
