Hope this wasn't posted before, but I was just watching the MSU vs. PSU football game from 1993, and they said something I've never heard of being done to the field. I guess there was snow on the field and the field had frozen. Now, I don't think that's that big of a deal and that you can still play on a frozen field, but apparently not. To Un-freeze the field they decided to use fertilizer before the game. They then play one half of football. During halftime they decide to wash the field off to rid it of the fertilizer. This just seems like a lot of trouble for something that doesn't seem like a huge deal. I would be shocked if this sort of thing still occurs or if it was common back in the day. Could Michigan run in to a similar type of situation where they have to warm the field up? Do they have some sort of heating under the field or another plan to prevent this issue? I guess this situation never occurred to me. Anybody else see this during the game?
EDIT: This also caused a good amount of water left on the field, which is another reason I thought it was so wierd.
