Explain what? Hanover Quay? Isn't that where their studio is, where people hang out and leave messages on a wall, and maybe Bono happens by and gives you a ride back to your hotel? (Which apparently actually happened at least once. Swoon.)
In general, I meant I wasn't planning on visiting "important historical" U2 sites, like a lot of fans do when they go to Dublin.
Zu - yeah, I'm going solo. Part of me wouldn't mind having a friend there to help figure stuff out, but at least this first time, I feel a big need to do it on my own.
If I ever go somewhere where I don't speak the language, I'd probably go with a friend or even a guided tour kind of thing.
