Just to add my sister has stables and I do ride now and again, I just don't like ignorant people doesn't matter if they are on foot, bike, horse, tractor whatever.... Like I said I kept a nice safe distance behind for quite a while, when the riders passed maybe the 3rd place they could have moved over and the biggest by far, then and only then did I move closer just to politely ask why they saw fit to just ride 4 abreast across a country lane
Ok once they just started abusing me then I told them they shouldn't be on the road, not as horse riders but as ignorant tw@ts
I agree moaning about horse poop on the roads is a bit silly and not in anyway relevant to laws on dog fouling
