OK - something bad is going on here....
Since I don't use "Pick Up In Store", I decided to just override the view in my Theme and took out the reference to it rather than wait on an answer. Just so I can keep moving forward. This did solve the problem (well...not really "solved" but made it go away)
But now I'm getting this:
One or more compilation failures occurred:
C:\home\site\wwwroot\Views\ShoppingCart\_CheckoutAttributes.cshtml(86,31): error CS1061: 'IHtmlHelper<IList<ShoppingCartModel.CheckoutAttributeModel>>' does not contain a definition for 'DatePickerDropDowns' and no extension method 'DatePickerDropDowns' accepting a first argument of type 'IHtmlHelper<IList<ShoppingCartModel.CheckoutAttributeModel>>' could be found (are you missing a using directive or an assembly reference?)
Why these unresolved references in nopCommerce views I'm not even touching? Surely, I've got something missing or configured wrong.
