I'm looking at the Street view around Ballybrophy and as far as I can tell it's the sort of area where enforcement against road parking and consequent reduced sighting distances would be a pretty good idea. Even better, a shuttle service between Borris-in-Ossory and Rathdowney (to the bizarrely located "Outlet"

)
EDIT: I am familiar with the roads around Rathdowney as I used to have a client in the area. Not so much business travel as rallying.
