In general, I have had a lot more luck on the Ticket Exchange for night games, especially if bad weather is predicted.
Sunday 1:00 games are turning out to be the games that you can't get tickets to from the Ticket Exchange, unless, again, they predict bad weather.
In that case then I am going to be doing a rain dance for the Texans game.....
Specially going to Boston that weekend so I am praying I get a ticket!
