Pilot "I am departing VFR from A to B. The current forecast for B indicates that a VFR arrival will not be possible, but C and D nearby are forecasting VMC. There is also an enroute forecast that suggests I may have to turn back to A. I have enough fuel to maintain VMC and land safely in any of these outcomes, and I am willing to depart to see whether conditions turn out to be better than forecast."
DFC:"Stop, do not depart, that is illegal"
Pilot: "Where do you make this stuff up DFC? Of course it is legal"
Fantastic!
