Hi Clive
It's not quite as simple, but I have classes here on Tuesday and Thursday evenings and the new monthly gathering on the first Wednesday of each month. I try to get to Auckland once a month for my aikido class there, on no fixed day, but haven't had much success lately. If I made my Auckland visits on Fridays I could be able to meet on Saturday or Sunday. Come to think of it, I am not very reliable because of the distance.
But if there was a regular meeting I would try to juggle my schedule to make it when I could.
Regards
david
