Have to agree with Irish Fire, Kildangan is hill billy heaven, there was a time when the "blow ins" would have been run out.
Saying that i see loads of new houses going up there and sure is probably just another part of Dublin now.
I dont know about the schools, honestly i didnt think there was any, my Mam lived near there and had to go to school in Athy (you dont want them going there), but that was years ago.
There is one shop and one pub and nothing else, its not a large town by any means.
BTW the motorway is a good 9 miles from Kildangan.
