I dunno, I have noticed that there are several properties that are addressed completely wrongly. I think they are leaving the placement of the icons for houses in the hands of the sellers; there was one spot located in the middle of Galway City, a site on Lough something or other, that in fact is halfway into Connemara. Also with all the development around Galway lately, the map is fairly out of date.
They should really do the placement themselves, and maybe do a deal with some of the GPS companies to get up to date maps. Actually that would be rather nifty, they could do an add on to the GPS software for live updates to property sales in the area, if you happen to be cruising by. Hmm...
