Goto the golf school that is attached to Ballentyne Resort Golf Course. You can park in the golf school parking lot and then walk down the cart path to the tunnel that goes under the street. Go through the tunnel. When you exit the tunnel leave the cart path and follow the line of trees to your right this will take you to a path that cuts through the woods and opens up to a pond that is on one of the holes(not sure which one). This pond is lunker heaven. There is a sign that states the 20 or so rules for fishing the pond. But as long as you dress decently, keep quiet, and don't disturb any golfers no one will give you any problems.
Make sure you bring heavy tackle
