Actually.....
A good few years ago I was in Co. Clare with a couple of mates.
We'd done a slightly naughty overnight in the grounds of what in the UK would be described as a stately home. No fires, no tents, just doss bags and kip mats under the trees (good wx for a change).
Next morning we met the groundskeeper.
"Ahh lads" he says as we walked by pretending to be interested in the flower garden. "if your after staying again tonight, keep well up above the road" (we'd been right beside it in case of having to move) "His Lordship" (that's what he said) "doesn't mind the likes of yourselves but some of the locals get upset" We did indeed stay another night and the groundsman came down for a chat, apparently the same family had owned the place for generations, waaay before partition and there had been a fairly major music festival there at one stage (allegedly with the Stones on the bill). In my experience that's a typical reaction.
I would however, and apologies if this is deemed contoversial, make an effort
not to appear like a Traveller, traditional Irish or "New Age".
