Still 35 more than Chicago's all-time record (1978) and a whopping 70-80 than another NFL stadium on average. ON AVERAGE. Minnesota went open air, right, same with all the others in snow areas. Detroit simply doesn't get the snow, it's protected in the winter...
ON AVERAGE The OP gets pounded, even more so than Downtown....
I don't dare touch my convertible below 40 degrees, let alone with tons of snow on top. I suppose they could heat it, to melt... IMO just not worth the hassle.
