Signs are there for a reason Lady Joan and yes, we all know stories about tourists that would stop and get out of their cars to have a closer look. Suicide when there is a lion and cubs around.
One of those leguaans swiped my moms feet out from under her with his tail when she went to collect eggs in the chicken coop on the farm.
Blessings!
Have seen leguaan around in a few places in KZN, never one this big, yes farmers lose chickens and small animals to them, they are clever, fast and powerful.
You will have to take photo's of the penguin crossing signs in the Cape one of the unusual signs we don't get.
