The MPSSAA website shows the dates but has the venue as TBA.
I personally think Towson (11,000) and Morgan State (10,000) have the perfect size stadiums for the finals. It was nice for the kids to get to play at an NFL stadium but from an atmosphere standpoint, I was not a big fan. At least at Towson or Morgan, you wont be playing in front of a 1/10 filled stadium.
