Last night's Diamond Grinding machine in action

The chicane is gone from Turn 1 and the track is now smooth after overnight diamond grinding. Average lap speed should increase now because Turn 1 is now a 150 mph bend instead of a silly 30 mph chicane. The weather is still hot and humid but Sunday promises to be much better weather as a cold front is supposed to move through this evening. Due to yesterday's delays, below is the revised schedule for Saturday – all times Central Time.
