Back to Dublin for an astronomy conference
Only a few months after my first trip to Dublin, I had cause to go back. It was the UK's National Astronomy Meeting, being held outside the UK for the first time.
I turned up half way through the week, and met a lot of people from my undergraduate days who I hadn't seen for more than two years. On a sunny afternoon when none of us had anything else to do, a few of us revisited the Guinness factory.
