Footnotes ...
| <1> | Our distances are not driving distances, but are calculated as a 'straight-line' distance.  A straight line distance ignores  things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Roslyn) to Point B.Our distance measurements begin at a specific point in Roslyn.  The point we use is located at these GPS coordinates - Latitude: 45.4966, Longitude: -97.4937        In this case, the coordinates for Roslyn have been provided by the Geographic Names Information System (GNIS). |  | <2> | If we encounter the name of what might be a community, our methodology is to add that name to our Gazetteer as a placeholder.  As we find more information about that community, it will be added to our Gazetteer. 
 Just as a reminder: Our definition of a community is rather broad and includes those places (or areas) where several families lived and had a name which identified that place.  For example, you might hear somebody say that they are going over to Mile's to see Pete ...  Mile's is just a gas station and a couple of homes at the crossroads.  While it might not be on the map, everybody in the area knows it by that name.
 
 Places of interest include buildings at a crossroad, several families clustered in a hollow or maybe the location of a way station.  It also includes places like mines, lumber camps, ferry crossings, etc.  The community might still exist, is now gone or only existed for just a short period of time.
 
 Also keep in mind that Roslyn could have been on the original document by mistake, misspelled, the original/alternate name  of a community that we've listed elsewhere or was placed in the wrong county.  Sometimes a post office or train station would have a different name than the community where it's located, so two names might be referring to the same community - we're working to straighten it all out.
 |  | <3> | An 'estimated' location is one where we have been given GPS coordinates, but are unable to verify the accuracy of those coordinates.  That said, we have some confidence that we have placed the marker near the actual location.  A typical reason for being unable to verify a location is that it might be on private property or maybe historic and gone without an obvious trace. |  | <4> | While we're fans and frequent users of TripAdvisor, you should know that we're also members of the TripAdvisor affiliate program. |  | <5> | The location has been supplied by the Geographic Names Information System - which is maintained by the U.S. Geological Survey (USGS).  While these values should be definitive, we found that accuracy can vary and you should double-check the location if accuracy is required. |  | <6> | While we have tried to pick reasonable speeds, the rate of travel is very theoretical - obstacles like fences, hills, lakes, river crossings and rest stops have been ignored.  When we say 'Days' of travel, we're assuming 8 hours of travel per day. |  | <7> | The shortest line can be visualized by stretching a string on a Globe from Point A to Point B - this is known as a Great Circle Route.  Where you might expect the shortest route from Roslyn to the Middle East to be East and South, the Great Circle Route actually lies to the North and East. |  | <8> | The calculated bearing (or angle) to Jerusalem is 321.339 degrees. |  | <9> | The calculated bearing (or angle) to Mecca is 319.699 degrees. |  | <10> | The calculated bearing (or angle) to the Vatican is 312.86 degrees. |  |  |
