A couple of times you recommended Vee Drive to me in the vicinity of Dungarvan. Is it easily accessble? How long does it take? Can it be taken "on the way" to Cahir?
You need my book! Everything you have been asking about is in it, along with complete descriptions.
The Vee Drive goes from Lismore to Cahir on the R668. You have to go that way anyway to get to Cahir. It will probably take 1 1/2 hours or more. It really depends on your driving style and how often you stop.
