Rabbi YM Friedman – for the uninitiated is the k’void kedushas sadigurer Rebbe and a member of the moietzes gedoilei hatoira.
He learnt in fallsburg was accepted into Brisk, and learnt in ponevezh, and is a musmach of R’ meir brandsdorfer and a massive talmid chochom – besides for numerous other ma’ailos.
He feels that there is mokom to be dan about the eiruv, but le’ma’aseh one should not carry.
I have put his opinions about shabbos shoes on RR’s other thread.
