When the aviator movie was out in 2005?, I believe the Houston Chronicle did an interview with one of Howard Hughes neighbors and class mate at school. I believe her name is Mrs. Pressler and she would have been in her early 90s.
I remember that building across from the Texas Department of Transportation and adjacent to Southern Lumber Company was called "Patroskis Deli" in the late 70's and early 80's. The owner of deli used to live in Timbergrove Manor just North of the Deli. Its been remodeled and of course, has another owner. Hope this helps!
