Not all that long ago...

Tranquillity won the Div V valley championship in Orange Cove.... I wasn't there but they gave me the video of the game. You could not see much further than half way across the field because of the fog... and I'm not exaggerating. On video the players would completely disappear just past half way across.

No doubt the QB's that night would have been unable to see a WR more than 50yds down the field. - JamesJM
