Professor Casey,
Thank you for such an informative response and accommodating offer. I cannot yet say for certain that I will be in Dublin as the specifics of my itinerary have not yet been concluded. However, I will do my best to see that I can make it to your city as I would delight in our meeting at least as much as yourself.
I have already taken your advice to seek out the Peter Harbinson guidebook of Irish monuments via a convenient purchase from amazon.com, and I will surely take a look at the dun of Dun Aonghusa and possibly The Hill of Tara as well.
With appreciation,
Matthew Moriarty
