I found out about another deal..
If you call up the ticket office and say "Family First", you can get $16 tickets (up where I am) for $8. It's part of a local promotion for WFAA Channel 8 TV here in the area.
It's actually good for all upper level tickets, but I believe you can use it for the $16 tickets in my area to get 'em for half price.
Here, check it out.
