I jumped on the river tonight for about 20 minutes.
The most precarious section of the river that I've encountered is near Arcola Mills. So that's what I checked out tonight.
There was some new open water and evidence of previous open water holes - frozen slushy piles of light brown ice. Oh, and the river was making some tremendously frightening low grumbling noises. But other than that, it was just fine.
With temperatures below zero at night for the next few nights, I think our Saturday night run will be great.
