Travel All Capitals of the Conterminous US States
Obtain the list of the capitals of the 48 conterminous US states.
In[1]:=

capitals =
EntityValue[
EntityClass["AdministrativeDivision", "ContinentalUSStates"],
"CapitalCity"]
Out[1]=

Download their GeoPosition coordinates.
In[2]:=

GeoPosition[capitals]
Out[2]=

Compute the order in which the cities should be visited to minimize the total geodetic distance.
In[3]:=

GeoPosition[capitals];
{d, perm} = FindShortestTour[%]
Out[3]=

Represent that path on a map.
In[4]:=

GeoGraphics[{GeoPath[capitals[[perm]]], Red, PointSize[Medium],
Point[capitals]}]
Out[4]=

Now compute travel directions to drive through the same cities in the same order.
In[5]:=

td = TravelDirections[capitals[[perm]]];
Represent the corresponding path on a map.
In[6]:=

GeoGraphics[{td["TravelPath"], Red, PointSize[Medium],
Point[capitals]}]
Out[6]=

The total distance to drive is shown.
In[7]:=

td["TravelDistance"]
Out[7]=

Compare with the geodetic distance.
In[8]:=

d
Out[8]=
