it's an annual thing Rez, the August bank holiday Sunday. It's in the large field to your right as you cross the bridge towards New Ross. I used to go every year when I lived in KK. Big show in a beautiful setting, right in the crook of the bend in the river, walled on one side by the steep forested slopes of Woodstock estate and the picturesque village of Inistioge on the other.
Jesus, I should be on the Inistioge Tourist Council
Alternatively the Stradbally Steam rally is on and always has a healthy congregation of classic cars for those not that interested in the smoke belching steam tractors...
