You beat me to it! Was just going to start a thread on this as I'll be in DFW for the arrival tomorrow as well. Too bad the winds are north..Would be good to catch from Founders Plaza. Hoping for Wunala Dreaming!!
If if gets 36L there is a golf course/recreational facility off of S. Airfield Dr. Take a right on Bear Creek Ct. Follow it around until you get to the entrance and drive down to the farthest parking lot. You can get some nice shots from that area. Not sure what time it arrives, but this area is for afternoon arrivals.
