"D500,
I see you are in Alabama. Is there a Crimson Tide and, if so, from whence does it emanate?

Mr Iron:
I stumbled across this thread again today, and I don't want to seem rude, so I shall answer by admitting that, though I am not only in Alabama, it's where I was born (Mobile) and have lived all my life (excusing a very brief stint in Winston-Salem NC), I do not care for football. There, I've said it. Don't tell anyone. I'm not even sure that it is legal to live here and not be a football fan. If anything, my sport of choice is baseball, and I don't follow that anymore, either. Go Yanks - believe it or not.
The "Crimson Tide" comes from the color of "Bama's" jerseys - red/maroon, and, I believe, and old radio broadcast from the 1930's(?), wherein the announcer described Alabama's line coming down the field "like a crimson tide". Or so I have heard.
The fact that here on the Gulf Coast there is sometimes a red plankton bloom out at sea that is often referred to as a "red tide" is not related to the "crimson tide", but it's funny, nonetheless.
Why Bama's team logo is an elephant is not known to me. Stomping and such, I suppose.
