1. Geographical features. Red earth (New Mexico), plains (southern Colorado), red mountains (again Colorado), mile after mile of highway and burnt grass (Kansas or southern Illinois), lush, fragrant, mountainous (Blue Ridge in North Carolina or Smokeys in Tennessee), are a small example of placement features.

2. City layout. Do the streets wander all over the place like Charlotte, North Carolina, or are they planned straight and at right angles like Phoenix, Arizona?

3. Street surfaces. Different locales use different ingredients in building of roads. Vermont roads are not laid with the same recipe as are South Carolina roads.

4. Architecture. Note different types. Do some of these coincide with ethnic background or socioeconomic necessity?
