This is an old cemetery at the end of Old Denton Road.    Google actually found the exact location but MapQuest did not.

Exit I-35W at Westport Pkwy/Keller Haslet Rd (exit 66).
Turn right (East) toward Old Denton Rd. (about 1/2 mile)
Turn left (North) on Old Denton Rd.  Cemetery is about 1 mile dead ahead.
