Found the beginning of a series of tunnels in Garland, TX. So far I have seen no other threads on this particular location. It is a water runoff system/creek that is beautiful to walk. One direction leads to areas covered in gang and occult graffiti while starting at this location continues up into Garland. At this point there are 4 tunnels starting at the back of a church and basketball court, 3 tunnels lead to the continuance of the creek while the 4th tunnel comes up on a two way tunnel split. I haven't ventured into Duke's Divide (named after myself) but intend to continue further later. While venturing down Duke's Divide tunnel there is no signs of graffiti so if you find and decide to push deeper in please be respectful by only marking directional instructions and appropriate and beautiful artwork. More pictures to come and videos will be available upon private request.
