BTW the baby chicks weren't coming from Michigan but going to. Also to add to my point I live in SW Colorado this past year we couldn't get food in from anywhere for about 3 or 4 days straight following a snow storm. Guess how they finally starting getting food in to supply the stores? I also know EAS aren't only in bad weather areas....I used to fly the routes so I know where they are.
I'm also guessing you've never flown in weather before because your response of "why would you fly in a blinding snow storm," take another guess. We all do it at the airlines from flying into ORD to podunk middle of nowhere down to minimums. Its part of the job and if you've never flown into podunk where the runways aren't always cleared, the ramp is covered in ice and its down to a 1/2 mile or less you don't have any clue what its like. I've had to shut down my engines while coming onto a ramp just to stop from sliding off into a snow bank because the ramp was one be ice rink.
