In my east coast days...
I tracked an 87 Turbo II, an 88 GTU and a 88 'Vert Turbo II conversion throughout the 1990s at Lime Rock and Watkins Glen. I managed to track my 87 Turbo II at Bridgehampton before it closed. Non-rotary, I tracked my VW in the late 80s.
Tracked my Miata and FD at Lime Rock once each in this decade but spent most of it racing karts and out of the rotary scene fixing my POS BMW that only got tracked once.
Now that I'm on the left coast...
Tracked at Buttonwillow and will be hitting most of the SoCal tracks in 2008 (crossing fingers).
