I stayed until they called it. I had a good time. The Cadillac racing ticket package was well worth it over the camping I did in 2018.
It seemed like the WTR car found some hp or grip at night when things cooled down. But it could have been that Alonso was just deadly consistent on his line. We walked the infield portion of the track for a few hours Saturday night and you could always tell he had more rpm leaving the turns than the other Cadillac prototypes.
The rain was interesting when they were running, but I would rather it have finished out in the dry.
