Tunnel Sends, Discriminations and Wraps

I designed the course below so I could work on turning Belle off a straight line to a tunnel and to work on sending Dusty into a tunnel without  head checking.

It can be used for speed laps as shown, with or without the bonus lines; for tunnel end discriminations (white #9 to black #1 or white #1); for tunnel/jump discriminations; and for wrap or tight work.
