Each cell is a square unit. North is up. "Next to" means one unit away, NOT diagonally. Although there are six categories, the locations are more specific. For example, if you find that Andrew St. is at A1, type "r" for road. If you find out that A2 is a golf course, type "a" for attraction. Any reference to "living" must be "h" for housing. Anything referred to is within the grid. A3 is considered store.
