Yes, this was the worst weather game I have attended in nearly ten years as a season ticket holder. The only other thing in the same ballpark was the blizzard game in Cleveland that I drove to. The sheer volume of snow for that elevates it, but I'd still take that over the freezing rain at the Giants game.
One of the reasons that game is so memorable for me, was that I left during the third quarter because I was literally shivering and couldn't wait to get home. Upon arrival my power was knocked out from the storm and all I could do was crawl into a cold bed in a cold house and hope my blankets would heat me up. It was horrible.
