It is not supposed to do this way down here on the bayou. This is the Gulf Coast of Florida on a bayou off of Choctawhatchee Bay. I looked out after about the first day of temperatures below freezing, well really in the 20's a couple of weeks ago, and saw an ice sheet about 2/3's of the way across our bayou. Wow. I have never ever seen that. My son took these videos later that morning when the sun was up good and it should have been warming up.
The first one shows him placing a golf ball gently down, because surely it would break the ice..right?! Then he tapped it...look how far it went. INCREDIBLE for here.
On the second one, he dropped it a bit harder. AMAZING!
