Craigs is sweet and odd isn't it. There's a mighty court tomb up on the hill above that I keep meaning to get to, but it's miles from any road!
That ogham stone looks very new to me. The markings are too narrow and not worn enough. Even ones that have been protected by being inside or buried for a long time don't look that good. They look machine cut.
What can be seen says LARATE, which doesn't sound like part of any inscription I've ever heard of.
(love your Haroldstown & Ballymacdermot-by-headlight images btw!)
