grinding at De Soto

So I see that the pavement grinding process is underway at De Soto Speedway. What will this do? Knock down the tallest bumps? Increase traction? How about tire abrasion?

This OTHER type of grinding takes place after the races, not during the week before the races.

The other half of the Pabst 12 pk is now gone, isn’t it?
