 How Far From Concord to ...We spend a lot of time looking through Gazetteers that were published in the late 1800's and early 1900's.  Many of the Gazetteers include the distance from a city such as Concord to various places of note, such as the White House. With a nod to our favorite Gazetteers, the straight-line distance beginning in Concord and extending to: 
Martinez, which is the Seat of Contra Costa County, lies just to the West Northwest.Sacramento, which is the State Capital of California, lies 51 miles [82.1 km]<2> to the northeast (NE).  If you could walk a straight line from Concord to Sacramento, with an average speed<6> of 2.2 miles [3.5 km] per hour, it would take most of three days to make the trip.  A horse and buggy averaging 3.2 miles [5.1 km] per hour would take most of two days.The White House (Washington, DC) is 2,409 miles [3,876.9 km] to the east northeast (ENE).  Driving, with an average speed of 63 miles [101.4 km] per hour,  would take 5 days, a buggy would take 95 days and walking would take 137 days.The shortest distance<7> to Jerusalem (specifically the Temple Mount and the Dome of the Rock) is 7,395 miles [11,901.1 km] and it lies to the north northeast (NNE).<8>The distance to the Great Mosque of Mecca (specifically the Ka'bah - or Kaaba ) is 8,161 miles [13,133.9 km] and it lies to the north northeast (NNE).<9>The distance to Saint Peter's Basilica (The Vatican) is 6,215 miles [10,002.1 km] and it lies to the north northeast (NNE).<10> 
Footnotes ...
| <1> | 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 Bird Creek to see Pete ...  Bird Creek 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 Concord 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.
 |  | <2> | Our distances are not driving distances, but are calculated as a 'point-to-point' distance.  A straight line distance ignores  obstructions like rivers, canyons, lakes, et cetera - it's truly a line  drawn from Point A (ie- Concord) to Point B.Our distance measurements begin at a specific point in Concord.  The point we use is located at these GPS coordinates - Latitude: 37.9790, Longitude: -122.0434 |  | <3> | We use the term 'Historic' broadly and it generally means that the community no longer exists.  However, it can also mean that the community might still exist, but was significantly larger or had a more 'official' existence in the past than it does now.  Unfortunately our sources of data have proven to be unreliable.
