I don't disagree with you and that's fine if people have flexibility in their plans.
However, for people who were planning to buy tickets ahead of time and bring family to town for it because it is much too expensive to do so for a real game, they can't plan ahead for that. Lots of people look forward to the spring game for that very reason.
Edit: I guess what I'm trying to say is it detracts from the family-friendly nature of the game as an event. Like I said in an earlier thread, I think they should limit the number of tickets that can be purchased by season ticket holders to 1 per season ticket and have them join the rest of the plebeians the next day if they want more tickets. That still won't stop the bots from buying all of the tickets within seconds of them being open to the public, though. That's where Kid Rock's approach comes in. Even with student tickets for regular season games, they check to make sure you are a student if you're using a student ticket (someone correct me if this is incorrect, my knowledge on this is nearly a decade old).
