After the New Year's trial, I set up the course on the left to work on 1) sending Belle to a tunnel and 2) having her turn off a straight line to the tunnel to a jump. Once it gets above freezing, I will bring out a short tunnel and set up the course more like this.
There are any number of sequences that can be run on this course. Here are four to start you off. Have fun, and if do set up this course, I'd love to see video of you and your dog running it.
