According to the article on the Cornell Hockey website, it says Lynah has been soldout for 50 straight games, including exhibitions. That's pretty hard for me to buy considering the three or four rows of totally empty seats in Section O against McGill.
Maybe students bought the section O tickets, and they snuck into the student sections to sit with their friends?
Just got four tickets from the Cornell ticket office for the game at Yale on February 12. This can be a tough ticket, so plan ahead. Standing room is usually available day of the game.
