Sorry Mark, thought you'd know
Here's the provisional calender for the Grand Prix Masters>>
13.11.2005 Kyalami South Africa
05.03.2006 Doha Qatar
16.04.2006 Shanghai China
18.06.2006 Monza Italy
13.08.2006 Donington United Kingdom 29.10.2006 Kyalami South Africa
Now you see why it's a shame, 14 days later is the 1000km LMES.
Monza is in doubt I presume
