Well it is actually the monorail building, the Skyride building is right next to it.  But you are right, the monorail has been gone for so long, I should be calling it the Skyride building to avoid confusion.  Better yet, I think we can officially start calling it the new roller coaster station.  I was thinking the same thing about the grass, but I am sure to Busch Gardens, spending some money to lay down grass now and have it look good for a few months is more important than having the area look torn up right now.
