It's a seven hour trip from Wilmington, so there's not tons and tons of slack there. It's unfortunate there wasn't a way to promptly get a replacement bus, though.
You are correct, it is what it is. There are few flights from that area to Washington and the surrounding area, and a replacement bus could not be found. I am in DC and was going to broadcast that game and Tom and Mark did everything humanly possible to get them here. Unfortunatly, it just couldn't be done. The game will be rescheduled for a later date and time.
