Ther are loads round there, I'm junc 20 of the M1, so am in the same area as you. Witham are good, have nice horses and reputable instructors. However there is also High Cross Equestrian Centre which is just up the A5 near Claybrook which is also very good, with very nice facilities.

My first pony had two wall eyes and i just thort it added to her cheekyness! it certainly wouldnt put me off buying a horse, i think they just add to their character! x
