In post 8 of this thread Marc suggested the 4th of June, this worked with our plans so we went up on Saturday. We decided at the last minute to see the exhibition on Sunday due to friends notifying us of their intention to come up on Sunday.
We didn't expect to see anyone from apug as we visited on Sunday and we assumed Saturday was the day. Actually spent some time taking piccies in the daytime and playing scrabble well into the evening, I lost.
Joachim, yep a pity it would have been quite nice to perhaps have an evening meal together somewhere.
