Leaking antifreeze.

I bought a 1993 Chrysler LeBaron Convertible with 67K original miles. It has a tendency to spew a cup or two of antifreeze about once a week. I replace new antifreeze back in the resivour but can't seem to tell where the leak is coming from other than the very front of the car.

Car doesn't seem to run hot and there doesn't appear to be any steam in exhaust.
