My current "to do" list includes buildings that:

(1) have been included in the National Register of Historic Places (NRHP),

AND

(2) housed (or currently house) financial institutions in the past. 

Here is my list in Excel spreadsheet format.

I plan to visit every single one building in the list in the next several years, and potentially may publish a book based on my photography collections.

I also created a customized online map on which you can easily locate these buildings.

Here is a KML file that you can use in Google Earth software.
