On Comcast, the Penn State game was blacked out as well. I went to check out the score as I was flipping around and they were simulcasting the Nationwide Race on ESPNHD (which was also on ESPN2HD).
Found the coverage map (most likely to be updated on the 25th for this coming weekend):
College Football TV maps: Week 12 - College Football - ESPN
Looks like I should have tried the Standard Def channel, or Baltimore's ABC affilliate (in Frederick, we get both DC and Baltimore's local affiliates).
@mooby: This past weekend was only the 1st or 2nd time the Terps were on TV (Raycom's Game of the Week) all season (not that I'm complaining because they've been awful). CSN is technically a Fox Sports regional affiliate, so that's why there are so many out of region games on instead of ACC games. ACC has some weird TV deals...
