Can you imagine, you slice a ball into the lake at a golf course and you see a sharks fin swim by? Better let that ball stay in the lake...... No worries this course is not here in the Northland, but at a golf course in Australia. Apparently after a big storm the sharks ended up in this lake and can't get out. Well, the golfers have been warned, they do have a sign NO SWIMMING with a picture of a shark on it. YIKES!
