FYI – For my first time, I just tried out this [Export to PDF] thing from ArcGIS to ship multiple layers of maps, and it worked great! Even Stan some non-techie users were able to easily turn on/off multiple layers and see/print only relevant layers of information from the PDF viewer, all without even opening ArcGIS. There were some tricky settings (e.g., including legend), but the process was relatively straightforward. This might be also helpful to hide raw data, when you’re limited to share sensitive (?) information around. Feel free to share your success (or not) stories too!
