Noon-40 degrees. Corn and ice. Classic track no good for climbing but in spots OK for picking up speed on double-pole. In the sun there's lots of suction going on. Your most beat-up bases will travel best due to their coarse structure. Fine structure bases are getting sucked down.
PM skaters were putting pretty big dents in the track. The blue trails were great for downhill: corn snow you can spray with a hard parallel turn.
Get it while it lasts.
