Just How Cold Was It?

So these are some of the random sights on the Detroit River.  A couple of them will give you an idea of just how cold it was today.

 The Lions had a home game, so this plane was advertising for a car dealer.

 And he moves on.

 This swan was taking a drink.

 And then he moves on.

 And then I noticed this.  Ice starting to form on the rocks.  The temperature read 21 degrees and the wind made it colder.

 It's not quite cold enough to freeze the river.

 But it was cold enough to freeze the water on the rocks.

 And the branches.

 And make some icicles.

And then I leave you with a shot of Detroit from Belle Isle.
