Razorback-Head West on I-40 to the Smithville/McMinnville exit. Turn left and go over the interstate. You will find Floating Mill a few miles down the road on your right. It has a campground and play area, also a beach/swimming area. There is some great bank fishing for bluegill there.
Also, on the same road is Hurricane day use area with some bank fishing places there. Center Hill is a great fishing lake, just don't give up on one try since water levels change on a regular basis.
Hope this helps a little and good fishing to you and the family. Love to see a family fishing together.
