Hi Mike - Thanks for thinking of us. I feel drawn towards Knocknarea[Maeves' mound] and after some dowsing up there, I am picking up at least four big lines crossing through the large cairn at the top[like Rory said]. The one that seems to head towards Newgrange/Anglesea direction appears to run through the middle of the nearby Carrowmore tomb complex. The link below is a map of the area . http://binged.it/UKAApo

If you look on the map -you will see a white dot just below where it says 'carrowmore'.If you zoom in,you will see that this is a tomb that lies in the middle of a whole[egg shaped]grouping of other ceremonial megalithic structures.
Maeves mound is on the big hill to the left -you can see a smaller cairn right next to it[north] -Here I am picking up a line that crosses through the two.
Happy flying Mike- I would be interested in what you can pick up on in this area, regarding large enegy lines. I will be returning to the hill soon for another dowse and will also check out the carrowmore site below.
