Work you way through the warm up

Warming up for a class at a show can be intimidating and distracting.  Knowing the "arena rules" can help you navigate through the traffic so you can focus on your horse and riding.
First, pass left hand to left hand as if your are driving.  If you are working on a circle and another horse/rider comes along the rail, pull your circle in and allow the other rider to pass on the outside.
If you are traveling in the same direction, the slower rider should be on the inside track.
And please, for the sake of other riders, do not stop on the track to adjust tack or talk with your trainer.
If you need passage (ie. diagonal) always say "please".
Courtesy and consideration are important.  The golden rule always applies!
