#' 
#' @description A \code{SpatialPolygonsDataFrame} containing polygons 
#' for the 23 counties in the state of Wyoming.

#' @format
#' A \code{SpatialPolygonsDataFrame} containing 23 polygons whose union outline 
#' boundaries of the state of Wyoming. Source shapefile was from the Census Bureau
#' in 2015; but, that shapefile has been taken down.  A secondary source of the Wyoming
#' counties shapefile, with different attributes, is here: 
#' \url{https://www.arcgis.com/home/item.html?id=65b84d3d0c59441596c900d24196d4fd}
#' 
#' Attributes of the polygons are:
#' \enumerate{
#'  \item  STATEFP = State identifier (56 = Wyoming)
#'  \item  COUNTYFP = Unique identifier for county
#'  \item  NAME = Name of the county
#' }
#'
#' The proj4string is \code{"+init=epsg:26912} \code{+proj=utm} \code{+zone=12} \code{+datum=NAD83} 
#' \code{+units=m} \code{+no_defs} \code{+ellps=GRS80} \code{+towgs84=0,0,0"}, 
#' meaning among other things that the coordinates are projected zone 12 UTM's in meters. 
#' 
#' The rectangular bounding box of all polygons is
