FYI

Floating the track means the tractors pull heavy plates (for lack of better word) over the surface which compacts the surface down to flat. they do this when rain is expected, so the rain will not penetrate the surface . If rain wasnot expected, i don't know why they would do such a thing. Track maintenance is something to pay attention to. They can change a track bias between races by harrowing in the opposite direction, etc. If you recall SB reported that they had scraped the inside at CD on BC day. for what its worth.
