Gonzo,
That slight dip looks something like;
2000: 466,815
2001: 463,568
2002: 466,554
2003: 463,650
2004: 475,999
2005: 477,884
2006: 477,030
2007: 481,356 (odd this last one as I am sure that is more than the planning allows!)
(Rounded down taken from ACI)
Mixed Mode, surely it will work haven't you seen the BAA presentation on their website!
All kidding aside should make the old place more interesting for a while!
