Oriole Park is a venue in or near Baltimore that is most often used for Baseball
The Orioles give out cool t-shirts, these cool little Budweiser hats almost every year, posters, mini bats, oriole keychains, and bottle openers.
They gives out great t-shirts and bobbleheads every year. There is one coming up for a Buck Showalter garden gnome that he's pretty upset about. They have some less exciting ones for floppy hats, replica (low-quality) jerseys and keychains too.
Floppy Hat Day!!! Those are the best and actually the most useful of all the give aways!
