September 24, 200619 yr Ken,Don't forget to couple whatever USGS you can get with the Census 2000 Tigerline shapefiles. These are far more detailed and up-to-date then the standard "course" ESRI.Here's the main map for downloading a lot of detailed shapefiles for many parts of the US. Info is organized by county: http://arcdata.esri.com/data/tiger2000/tig...ty.cfm?sfips=02 Randall Rocke
