As I mentioned below, I walked along the seafront in Dun Laoghaire today. I love walking there, especially on a day like today. Saw quite a few tourists, including a few from the US of A. You can always tell the tourists on a day like we had today. They're the ones who believe you need a sweater or light jacket when the temperature is soaring to 60 or so with that fairly "fresh" on-shore breeze and the occasional threatening looking cloud. The locals think that's shorts and tee-shirt weather.
The views along the seafront are tremendous. I never tire of being there.
That's "James Joyce's Tower" in the distance. If you're one of the few who's read Ulysses you'll understand and if you haven't then it's still a nice picture.
And that's Howth, Co. Dublin way off in the distance. The rocks you see in the foreground are part of the defenses of the Dun Laoghaire Pier - a great walk, if you have the time.
