This is a good list:

I don't think I'll tick any of these off in 2015, although I'll be going to a new one in a couple of weeks. New Zealand festival of motor racing at Hampton Downs with a big contingent of F1 and F5000 on show. That and the usual PI/Sandown/Winton historic meetings will probably do me for 2015.
What are youse all going to see in 2015?
