Obviously depends on crop and circumstance. What you say is often true. That said: if it's early spring and I have the choice between an Oregon-grown apple and a flown-in New Zealand Fuji (or Chilean/Peruvian asparagus, often available and yummy during the winter), there's really no contest.

Does that make it "good" to eat the airborne food? Certainly not by many measures. But you can't just pretend that "local == better" if you want to win arguments either.
