Well i was hoping to figure out if there was any alignments with the passage tomb at Shrough. If that doesnt work out then Ill probably head over to Knockroe (maybe on the 20/22), although I dont recommend being there for sunset on the 21st, there are too many people there.
Although there is no real alignment as such I may head to the Grange Lios at Lough Gur for sunrise on the 21st. I hear there are normally a few Druidy types there and Im kinda in the mood for a bit of that this year.
All weather dependent of course.
