Lessons learned on the trail . . .

are some times hard to take. I have MANY riding pet peves. One being watching a rider trying to get on as the horse is walking off. Another is adding MORE equipment to to "fix" a problem horse. AND ANOTHER, is riding with people that have NO control of their horses mind or body.
The people that are on a group ride and complain of  "other" riders causing their horse to act up because everyone isnt riding nose to tail. If you have control of your horse, how I ride should NOT affect your ride.
 As long as you maintain trail etiquette, "passing on your left/right", No running off in front, through or next to other horses. (running/trotting/loping BEHIND the group is acceptable as long as you DO NOT run UP on the group or other horses) and LEAVE AT LEAST a horse length between riders. NO RUNNING up hills past or into other riders.
Riding in a group is similar to driving. Watch the other riders and know who to avoid.
Defensive Riding! (which means YOU have to be in control)
