the metro beach back basin is in metrobeach metro park. Basically take 16Mile road (metro parkway) east and it goes right into the park, hence the name. It is like 4 bucks or something to get in. once you are in, take a left and that is the back basin. If you need bait take a right at jefferson before going into the park and there will be a bait shop/party store on the lefthand side basically right there.
