If you have never been to Sea Turtle, Inc. in South Padre Island, it is worth a trip. Their efforts to save the turtles is amazing and beyond what you could imagine.
They recently purchased the land between the existing facility and The Birding and Nature Center. In addition to education facilities, they intend to tear down their old amphitheater and build a new one. They will also have 4-5 large tanks that will house some of the non-releasable turtles and much more.
