Basically the neighborhood is a 3 by 3 square, and there is something happening with every way either going up or down. Some ways are not available due to steep angle, lightning etc. And remember to watch the caller's heart rate.
The ambulance is on York Rd, I found it by going right towards Rothrock first, then turn right twice all the way to the end, which is York, turn right pass Thompson St, and there is a "buzz"...
I'm still trying to figure out what if I turn left and straight to York...
P.S.: After the skill there is a strange moment that mentions "SIM CALL", then a glitch, and CALL TERMINATED.
A lot is going on within this part... still need more time to find out more info.
