I looked at the webcam for GTB today and it looked like the marina had frozen, or maybe the camera wasn't refreshing.
Earlier this week, on Tues, I went out at 0 degrees for work and at the end of the day it got up to 19, then Wed, started at 19 and went to 35. I haven't done outside work in this cold of temperatures before. I made sure I had plenty of cold weather gear on to stay warm and it still wasn't enough. I'm in the military, so each of those days we went out to shooting ranges. More field work to come next week too
