That's a pity Roger, but we all have to prioritise when requested
If I go, it will only be for the 'talk' at 20.00 hrs, and not the astronomy class, prior to that, as I've already got that 'T' shirt.
I note that there's a 'hands on workshop' at the Murdoch venue this coming Friday. Not sure what this is, but I may go along and see, if its ok to do so.
