Converted the map to some other useful things for those that are interested.

Attached is a zip that contains a gpx file and a kmz file. The kmz is importable for google maps, as the gpx can be used with garmins and many other map and track applications.
If you want to use google's My Tracks app on android, then
here are instruction on how to add them. It works best with the gpx file than with the kmz/kml.
The other app that I prefer for this kind of thing is
OsmAnd as it's free and has a decent usability. I use it only for creating tracks and following tracks. You will have to download the texas map, but that shouldn't take too long from your home wifi.
I don't own an iDevice so I'm not familiar with any apps that would do the same kind of things.
