In Philadelphia, there was a fun thing at the baseball game. You could get hot dogs for one dollar. But now, they have stopped this, and instead, you can buy one hot dog and get one free on two days in April.
Last year, some people at the game threw their hot dogs, and it was messy. There were too many people and it was not safe. So, they had to change it.
Before, the team did this to get more people to come when it was cold or rainy. But the team is good now and lots of people come to the games. Still, they want families to have fun and not spend too much money on food.
Other places still have cheap hot dogs. In Pittsburgh, they have hot dogs for one dollar on six nights. In Kansas City, they also have cheap hot dogs.
But in Philadelphia, you can still catch a free hot dog if you are lucky. The mascot shoots hot dogs into the crowd with a special gun.
