I kinda figured it was a result of the conditions. I forgot that this is the dry season out there. (Like the fires aren't a dead giveaway

). I'm just surprised that even with it being so dry that the sun doesn't have more of a detrimental effect. 4.40's in the sun is amazing regardless of the air. Imagine what they could do at night out there if they ever had the chance.
I just wonder with all it's potential and ability to produce good numbers combined with what are basically predictable and consistent conditions for the most part, why wouldn't they make it all concrete like Joliet?
Afterall, this
IS the NHRA's home track with a rich history and two prestigious races. Plus it might help keep the lanes more equal and also give Joliet a run for its money. Even in marginal conditions Joliet still produces stout numbers. In Pomona they're pretty much the same from day to day.
Does an all concrete track not work well in other parts of the country? I know it's much more expensive but they also last longer too if I'm not mistaken. I'm curious as to why more tracks don't make the whole 1320 concrete. Seems like it's make for better racing not having that dreaded transition from concrete to asphalt that seems to plague so many teams during the warmer races of the season.
