There are lots of high school football all-star games and you can add another one to the list. Technically, the Chesapeake Bowl is in its second year, but it's still relatively new.
The game, according to the website, features high school players from Pennsylvania, New Jersey, and Delaware (North) vs. players from Maryland, D.C. West Virginia, and Virginia (South). This year, the game is on December 30th at Bowie State University in Maryland and since it involves a bunch of local kids, Pitt, as expected, has several players expected to suit up.
Tickets aren't too bad and if you're in the area, might be wssorth checking out.
