If you ever want to come up north, I am game to go riding.  Area is between 75 and 77 on the E/W sides, and 380/82 on the S/N.  Lots of county roads with relatively light traffic, not too horrid chipseal, and plenty of refuel/rewater stops.  I am in McKinney.

Greetings another rider in my area.
 
Cotton belt is a great trail that can be used to jump off into all kinds of riding in Keller, southlake, grapevine, Roanoke and of course hurst.  I live just a few miles from the south end of it and ride it occasionally, but do ride all over the area.  Not a mapmyride user but use Strava, endomondo, ridewithgps garmin connect and can share routes with you from any of these.  I ride the area most every weekend at distances from 25-100 miles, there are also several shops in the area who do Saturday morning rides, bicycles inc, hurst, knobbies and slick colleyville, bonzaicyclewerx ft worth(my favorite and a catrike dealer).
 
Pm, let's see how I can help you.
 

Have you tried Strava route explorer?
 
Might be a way to find routed others have stored/frequent near you.
 
Bicycles inc hurst might have routes they can share with you.  You might ask them for a wknd ride map etc
