Regarding the BWT.
From what Bing reports the owners are having difficulty getting their heads (there's that "head" word again) around the accreditation.
If they can get accreditation then what is to stop them running a Wine Train on the suburban lines? By the time pax did ARS, Belair, Gawler and return they could be well pickled with SA wine. Make a good afternoon's outing. Evenings could include a meal. No reason why canapés could not be served in the Heritage shed at Belair and a main course at Gawler in the heritage building.
