The Cush

Honu - some of the grumblings I have heard from Jocks in KY is that you cant hear when a horse is coming up on you when you are in the lead. They say when they are on the lead they constantly have to look under the arms or over their shoulders to see where the others are. Also, they say that the horse doesnt hear the horses coming so they dont get the sense to "dig in." What is your opinion on this?
