Do you remember in the movie Cast Away with Tom Hanks when he was planning on sailing over the reefs but he had to wait until the winds changed? In the movie Hanks character fervently watches a ragged flag flap in the wind which, in a dramatic moment, shifts direction before his eyes indicating the change in the season. I always thought that was so cheesy but now that I have lived on an island I can say it is exactly like that - one moment we are watching monster waves crashing on the north shore and then the next day it is spring and the ocean looks like a giant farm pond. Weird.
