The athletic dept will be having special promotions throughout the season. Many of these are well worth the $$$s for a family. IIRC something like 4 end zone tickets along with a couple of items from the concession stand for each ticket for $10.00 each. Hope I'm not too far off in this example. Check the athletic dept web. site (GoblueRaiders.com) or listen to Chip's "Blue Raider Report" (on Monte's show - Chip's segment is on at approx. 5:30 each day - WGNS) throughout the season.
As an aside: I'm glad you are wanting to attend MT games and at the same time want to save money for your family. I get it, I really do. But, to this long term season ticket holder in both FB and BkB the promotions devalue my season ticket purchases. It is really frustrating to see that the only things one gets from buying season tickets, along with knowing you are helping the program, is a reserved seat and not having to stand in line. MT is, as far as I know, the only athletic dept dept. where if one buys tickets to every event at the lowest price available on game day they will save a considerable amount of money compared to season tickets. That, to quote my favorite uncle, Just ain't right.
