Its a decent hike for NTX. Parts of it go through fishing camps (Paw Paw, and others) so its not like it is real remote or anything. I caught enough fish for a couple of meals as the trail is adjacent to Lake Texoma most of the route. There is a designated campsite about halfway in, if I recall correctly. It would be pretty quiet this time of year. The only hazards other than the lake for solo hiking is poison ivy by the bushel. Check out Hagerman Wildlife Refuge for some good exploring and excellent birding. Any of it beats TV and hanging out in the Metromess.
A nicer area, but with a less developed trail system is north of the border near Tishamingo, Ok at the Blue River. They release trout there in the winter also. The campground is a bit rough and its a public hunting area so know the season. The best hiking in that direction is the Wichita Mtns near Lawton. Another good Ok option is Beaver's Bend and Broken Bow Lake about 2 hours NE of the Dallas area.
