While I'm absorbing the material from the GAS Conference, I wanted to post this about the Glencairn Museum. Ken Leap has been involved with them of late and it's an amazing place if you are interested in stained glass at all. I visited there some twenty years ago and would love to make another trip soon.
Highly recommended.
