Regions of Mallettbarr

Image
  The geographical regions of the U.S. state of Mallettbarr (click to enlarge). There are seven distinct geographical regions in the U.S. state of Mallettbarr. Unlike other states, Mallettbarr's regions do not necessarily have their own culture. [a] [b] Blandsands - Think some parts of the Australian Outback and you'll get a tame version of that here. This region is quite a bland version of that part of the Land Down Under - true to the name "Blandsands." Eastern Prairies - Unassuming fields of prairie grass, farmland and small towns and villages as can be seen in states like the Dakotas, Nebraska, Kansas, Iowa and Missouri. Finanthia - Woodlands, farms and ranches adorn this part of the state. Think Kentucky and much of the Pacific Northwest. Outwater - This is as close to "tropical" as you're ever going to get here in Mallettbarr - Outwater is so named for its location out at sea. Ferry to and from Nantwich Island takes about 45 minutes.

A Basic Guide to Highway Markers in the United States

Image
  The highway markers used by all U.S. states and territories, as well as the Interstate highway and U.S. Route shields (click to enlarge). Many state highway markers are designed with the respective state's geographic shape in mind, or are based off of a particular state symbol (i.e. the highway markers used in Kansas are sunflower-shaped, as the wild sunflower is the state flower of Kansas). Most of the U.S. states use generically rectangular or neutral shape for their state highway markers, and the circular highway shield (which is how state highways are indicated on most maps) are used by the states of Delaware, Iowa, Kentucky, Mississippi and New Jersey and the territory of the U.S. Virgin Islands for signage on their respective highways. Generally, state highways are low-capacity thoroughfares that run across the state or in specific localities, although some state highways are built as expressways or up to Interstate Highway standards if the traffic volume on the route is su...
