What are your pet peeves? Here's one of mine: At the start of an endurance ride (LD) -- someone waits until the main group goes out and then at about the 2 mile marker BLASTS past those who really did want to go out last (perhaps starting a new horse!) -- ESPECIALLY on a stallion!! (you know who you are!). WHY WHY WHY??? If you are going to blast down the trail, WHY do you start at the back???? I guess it's just another example of rudeness and lack of common courtesy.
