Ok, who am I to question Greg's knowledge.

I looked at a track map I have at home from the Mid Ohio schools & the turn David & others are talking about is TURN 13.

Next I went to the Mid Oho site & they say:

Mid-Ohio Sports Car Course is as friendly for the fans as it is tough on the competitors. With two configurations – a 15-turn, 2.4-mile layout and a 2.25-mile, 13-turn version.

Now if the 15 TURN course is being used as it will be when Marty is there this weekend & you subtract TURN 15 & 14 you will have the TURN 13 that David & others are talking about.

Have Fun
David

ps: If anybody had any common sense when the 13 turn course is used they would just drop T 2 & T 3 from conversation & call all the remaining TURNS the same as when the 15 TURNS are being used. IIRC from last years Runoffs that's just what they do.
