My first born is 24 years old, so I'm pretty sure it's illegal to try to sell her.
The Orioles prices seem tame compared to other stadiums. Maybe because they know no one would pay outlandish prices to see them. Here's the pricing chart.
I don't know how they can get away with having higher prices for "prime" games. I don't remember them doing that before. Then again, I've only been to one game at Camden Yards, and that's the year after it opened.
