Some one had arranged for the tour to start in the western suburbs
(possibly Penrith or Richmond), pickup at P'matta and Hornsby, and then
procede to Broadmeadow. At Broadmeadow we boarded buses and took a tour
to Wyndham Estate in the Hunter for wine tasting.
>From there, it was back to Broadmeadow, then return to Parramatta.
This still does not confirm Richmond, but may trigger a memory in a
follow traveller.
Cheers, Gabi.
