Please don't forget the importance of manners to other road users whilst out riding. If a car slows down for you, please remember to say thank you. If you have your hands full then acknowledge with a nod and smile. Unfortunately there are drivers who do not understand that horses can be unpredictable, or they are in a rush to get from A to B; so please, don't miss the opportunity to acknowledge their courtesy.
A simple THANK YOU goes a long way!
