@Armata, can you remember if it was the german guy who owned the guest house or his friend john (I think he said). The owner wasn't certain but informed me that his friend was the one more into snakes.
Nvlooi, the project is focussed within the boundaries of the city of cape town which extends from Kogelberg in the east, before you reach rooi els, up to around blouberg in the north and everything in between. This includes places like Kenilworth, Rondevlei, Tygerberg etc but not the table mountain range really as that is managed by sanparks, although data from it would obviously be useful.
