Le Mars

Explanation of city layout: Take LeMars and divide it equally into four sections with Plymouth St. being the road that runs East & West and Central Ave running North & South (imagine a plus symbol for these two streets.) Everything in the upper left hand section are numbered roads ending in NW, the upper right section end in NE, lower left section are the SW roads, and lower right are the SE roads. All North/South roads are Avenues (they run parallel with Central Ave) and all East/West roads are Streets (they run parallel with Plymouth St.) .....this explanation courtesy of Cyndi Taylor.
