There is a cable at Bethy Creek but it's not a 2.0, it's a new two tower system (
www.endlessridecable.com) they are using for a summer camp there. It's open to the public on weekends and by appointment on the weekdays during the summer so you may want to call them. If you want to try something different, it's not a bad drive up I-45 from Houston to get there (near Huntsville) Hope that helps!
