MetroNorth Ambulance stood out, our buses were purple. You want to talk ugly, we'd roll up on an MVA and patients would refuse to ride with us because our buses were so ugly! They'd rather die in the street than get in our ugly bus. Thank goodness they were bought out and given a white and blue paint job :0)The fact you find them ugly may be the reason they went that route. I had a supervisor at one of the hospital based NYCEMS facilities that used an ugly scheme also. His idea was that it knocked down the number of complaint telephone calls he got because his units stood out against all the other ambulances operating in his area when his units were doing something bad traffic wise.
