General Deansgrange info (based on memory and what I've heard since I've moved away):
At the main crossroads, which is Deansgrange you have a SuperValu, chemist, chipper, AIB, newsagent (used to be a post office as well, don't know if that's still there). I'm missing something, I think there's on more shop there. Across the road is Bank of Ireland and Lidl (or maybe Aldi) and the library. Deansgrange Motors and a pub on the other two corners. Texaco up the road on Clonkeen Road (still there? So many garages have closed down). Bakers Corner short walk up the road from there with an Aldi (or maybe Lidl) down Pottery Road - convenient driving distance but not walking distance.
On or near 45, 46A and 75 routes.
I went to school in Rockford but that's a long time ago - there's only the secondary school left now and the nuns are gone as long as I am. Lots of friends still live in the area and find it handy enough.
