In the past when all was well you could make as many laps as you wanted, some nights 20 passes were easily a possibility. It is true they may be taxed a bit with more than usual people showing up. They tend to not ever start at 6pm. So maybe when in tech inspection ask if they are going to start on time...if not ask why and suggest they get with it (as advertised)....the light will be almost gone by 8:30pm now. Several things could slow or stop the action, so I suggest you not dawdle...get as many runs in early that you can....if all goes well you should be able to get quite a few runs in if you want. Look forward to seeing you guys out there....I will spend some time at track level with my camera, shadows can cause photo difficulties, but will see how it goes.
