Me: Hi, First off, I would like to thank you for the free tickets for Soldiers. The Tri Cities is home to me so I made the 4 1/2 hour trek from Fort Bragg and was glad I stuck around for the whole race. My question though is an odd one, but something that had my friends and I curious. Between turn 4 and the start/finish line there was a small line down the track that officials were drying with leaf blowers. The jet dryers and Air Titans would speed over this line, so as to not mess it up. We were just incredibly curious as to what it was, and I have been unable to find anything about it through online searching. Thanks in advance for your help, and again, thanks so much for the Soldier support and the free tickets!
Kevin Triplett (VP Of Communications): Bill,
 
Thank you for your note and, even more, thank you for your service.
The area to which you refer is a section of the track where there is a scoring loop  the electronic timing system that records where cars are and in what position on the track. There are somewhere between six or eight around the track, not counting the timing sections on pit road. Cuts are made in the track, the fiber is laid and then resealed with epoxy. The tremendous force of the jet dryers and Air Titan could have damaged the loop if they lingered over the area too long (and created even more problems). But because of the cut in the track, even though it is very small, it acts as a small drain. So, left unattended, there would have been a wet spot there at a critical point of transition on the track. So that area was maintained with the leaf blowers.
I hope this explains things and thank you again for coming to Bristol. We hope you return.
Me: Thanks for the swift response. We suspected a timing loop, but wondered why it was the only one getting such attention. I appreciate the information though and look forward to returning!
Kevin: That end of the track drains differently, that area of the track especially, so that created the special attention. 
Me: Makes sense to me. Again thanks for the answer and for the hospitality.
