Dear Dr. Bill,

I think they have ways of dealing with them at airports. You might, in the meantime, get some amusement out of this website by the people you call "bleeding hearts": http://www.icu.com/geese/coalition.html

Here's one about how to keep the populations under control: http://www.fw.umn.edu/research/goose/html/airport/inter1.html

There's actually lots and lots and lots of info on this (I googled "Canada geese airports" if you want to try it yourself). I don't have time to look through them all just yet. But you're right, they do seem to be somewhat of a problem at airports.
