Narrowest I've landed on was Coonagh just inside the Shannon zone by Limerick, the tarmac was just wide enough for the wheelbase of a PA28.
You had to buzz the cows first, too. I wonder, does the field still exist?
Coonagh is still going strong. LFC is probably one of the stronger clubs in Ireland at the moment. I learnt to fly there myself not too long back and it's a really enjoyable field to fly out, good for practicing go arounds.
You'll be glad to know that the cow's are doing well and fattening up nicely for next summers barbeque.
It's not that narrow either as you can see from this video I only needed half the width.
Although be aware that if you are used to much wider runways it apparently can appear that Coonagh is a lot longer than it actually is(416m).
Or if you're like me and used to flying out of Coonagh you flare at 50ft on the wider runways.
