I highly doubt that any Tzeddaka collector coming around after Shachris is collecting for the Fund to FLy the Satmer Rebbe.
As for your comment about Rav Shach.
You are quite mistaken, Rav Shach lived right near Yeshivas Ponovich and not a 2 hour bus ride from yeshiva, he usually walked the short distance.
BTW there is probably no 2 hour bus ride in the entire Bnei Brak!
