Last night's truck race had to be the most annoying race I've been to in person, weather wise.
I wouldn't call most of it rain, more like an annoying mist. Finally, once it did start raining, we lost the track. We left during the hour long red flag, and thankfully didn't miss much.
We listened to race control on the scanner, which was very informative. Race control was constantly in contact with the pace truck, relaying conditions, and also talking to the clean up trucks during the cautions. Before letting them go back to green, they checked with the spotters stand and got the green light from the group of spotters. The insight into the process was very interesting.
