April the second is good for me, although I do have reservations about an inner city meeting as Ralph posted a preference for a day outing.
I have met up with some APUG people in Germany where once they came around to my place and took me out for the day, the second time I took a pre-dawn train from Munich to Stuttgart to meet up with them. Both times were memorable.
What I was shown both times, was stuff that was interesting to a photographically orientated outsider. If Ralph is domiciled in Richmond, which is almost inner Melbourne, he can take public transport to central Melbourne and be there in 12 minutes.
