That is good news.
I tried to find some historical data to see just how ahead of schedule we might be and I found this blog post on Sawbill's site from two years ago. Just eyeballing the chart, I see a lot of data points just to one side or the other of May 2nd. So if we use May 2nd as the median, we are maybe a week early. Still, it is not all that early considering the mild winter we have had, and not an abnormally early ice out.
