Sandi, it always pays to be careful. A niece of mine bought me a crocodile warning sign she put beside my dam. However, there is a 3 metre (9.84 feet) crocodile that visits my place during the wet season, plus some smaller ones. I'm just extra cautious during that time of year and warn visitors who may think the sign is purely a joke.
Whilst first starting as a Crocodile Cubit, questions/comments about other reptiles made me decide to broaden it to other reptiles as well, and frogs. There's very many groups and species but I'll cover what I come in contact with and photograph.
