you guys gotta be kidding.
there is an ambulance parked on south street right near the little tunnel that leads to the BBT. people in the wall street area leave their job if needed and respond during the day. there is a division on the lower east side; upper east side; west side and yeshiva university area.
they answer loads of calls. i find it surprising that some have never seen a hatzolah ambulance in manhattan.
matter of fact, come to the salute to israel parade this coming sunday and you will see multiple ambulances there some of which are manned by manhattan members as well.
