18th sounds good to me. Everyone talks about the track being at its best just after the races, so I was originally thinking of hitting the days following the races, but I'm game for either. Did you do a novice school? Normally they keep you pretty busy...not sure how you could get bored with the running to and from the classroom. My second trackday, i was bored between sessions, but that was because I didnt bs with anyone till the day was pretty much over. Once you start to know the people who are pitting around you, there isn't enough time in the day.
