Location of Arlington, Texas
Arlington applies mostly to The Multiple Nuclei Model due to the fact that Arlington is more scattered then built in an organized fashion. I found there to be high-class neighborhoods next to middle-class gas stations and apartment buildings. At the same time I noticed that the construction sites were mainly in the low-class areas.
The image above shows one of the many boundary signs I saw driving through Arlington. All of these signs were placed in similar areas, urban wise, all being either in an intersection or on a highway, they were all next to busy traffic.
