I'm scheduled for a trip to my father-in-law condo this winter. The condo is located in Fort Lauderdale. I will pass two weeks there and I don't want to stop my tri training sched. There is an artificial lake in the center of the complex. I saw some peoples swim there before, but with a recent posting about snakes in the water...ehhhh...I don't feel very secure to drop myself in these waters....Please light me up on what sort of things I can encounter there...Thanks Florida guys.
