Notes:
- 
Visualize two trains passing each other on opposite direction tracks:  - Beaus on outside track;
- Belles on inside track.
 
- 
In your unit, you have a Leader and a Trailer.  
  The trailer can place a hand on the Leaders back, then proceeding like that, 
  the First Couple does an exaggerated Partner Trade as others follow them in 
  single file, stepping forward to end in Parallel R-H Waves.
- 
Track 2 is equivalent to  Tandem Partner Trade & Tandem Touch.

Cheat: Leaders Trade, Pass Thru, Trade By, Step To A Wave.
