Stashing it in the bush certainly beats throwing it away. On our Cape trip two years ago we stood inside the shop at the Jardine ferry and watched a group pour six bottles of unopened spirits on a tree out the front i almost cried. I took only what i was allowed although some locals told me that as we were staying at Punsand we could have got away with the bonfide traveller excemption. Not sure how true that was as i wasn't taking any risks. Good to see the authorities enforcing the Law.
