-While it is frustrating that the prices are rising, there are ways around this. The type of game is an important factor to include. Obviously rivalries are going to be expensive, but if you go to maybe a Wednesday night when your team plays someone out of market, you can grab same day tickets for a deal on broker sites(although fees are annoying). I believe there are ways to be creative about this, and doesn't necessarily have to break the bank(I paid 6 dollars to see the yankees play the marlins like 3 years ago as an example).
-The food portion I do agree with, as that is getting out of control. I tend to eat before I go and stick to waters(maybe a beer or 2) to not spend too much while there.
-Given the subway system in New York, I've never had to park a car to get to a game and pay round trip 5 bucks to get to the game, so I'm uneducated on this one. I am sure this is probably the hardest cost to avoid in most cities.
Last thing I will say, as I know my prior thoughts don't necessarily address the obvious problem of major league games becoming out of reach for groups/families.
When I was a kid, one of my favorite games I've ever been to was a Minor League game in Newark, NJ. For a low price, you can get GREAT seats and the same environment of a baseball game. From what I remember, it was a fantastic family environment, that tends to offer cheaper amenities(i.e food, drinks, etc.) that still provides a great ballgame environment. Know this is not the same as seeing your favorite big league team play, but still a great option!
Would love to hear what people think
