  curbs-extra (the other corners' kerbs, outside kerbs and unnumbered bends)
  apex / apex-extra: kept empty (no apex dot is drawn)

NOTES
  Kerb strips were marked by hand from the aerial photo. The outside kerbs at T10B and
  T6 and the kerbs on 12 bends without a number were marked by hand from the aerial
  photo. T10B has no inside kerb. Pale grey fills are paddocks and lots, grey-tan
  bands are service roads, mid grey fills are buildings, sand-coloured fills are
  gravel and sand traps, pale blue fills are water; dotted grey lines are walls and
  fences next to the track, thin grey lines are access roads. North arrow on every
  page.
  A chain of small grey rings is a tyre barrier; a grey band with a white centre is an
  airbag or soft wall.
  Elevation strips: the whole lap on the cover (feet, S/F at both ends, turns ticked) and
  the drawn stretch on each corner page (grade in percent at the apex, crest or dip marked).
  Not for navigation; verify references on site.

CHANGES
  v1.0: first edition, drawn by hand on aerial imagery (lap 2.14 mi measured);
  start/finish placed on the painted line; reference features, north arrows and
  elevation added; corner numbering set by hand (see TURN NUMBERING); every page keeps
  a blank 3/4 in strip along the top edge for a hole punch.
