That was at Huntsville (Alabama) Dragway last weekend. The track prep was good and the air was cold. The racers had to endure a Friday that was rainy all day after getting there Thurs afternoon, and make up for it by racing Sunday after the cold front came through. I think both 315 and X275 records were set there. BTW, there was a little headwind.

My home track. Were lucky it is still open. They used to come to HSV to set records and now the tradition continues. In N. Alabama track prep has been a competition lately.
