Thinking of the "Robyn Rae" reminds me of Sunday School Picnics. I may be wrong, but I seem to remember one involved the "Robyn Rae", although I'm not sure how as not everyone would have fitted on it. Most picnics seem to have been held at Mossvale Park near Mirboo North. We sometimes went in a furniture van - although that seems a rather precarious way to travel. My good friend Pam Ratten and I used to climb a tree - perhaps this one - and pretend it was The Wishing Tree from Enid Blyton's stories.
There were also three-legged races, sack races, potato races, egg and spoon races to be enjoyed.
