QuickMap has some excellent maps.
For example, mouse over the 'full system/frequent/very frequent'
buttons on this London map.
With a good map, you can ask and easily and accurately answer,
Where can I go from here ?
To go there, where can I start from ?
For a complex system such as the London Underground,
Which line should I take ?
Where should I transfer ?
CostCo is a warehouse style big box retailer.
The goal is to find a CostCo near you (assume you are in zip code 63011,
or Clarkson Valley, MO).

Search by town and state, or by zip code.
This finds a reasonable list of CostCos.
The results show the CostCo on a map with detailed context,
and the results list each address. All good so far.

Selecting the South Saint Louis link brings a page exclusively about
that particular location.

Note that
1. The location's street (Rusty Road) in not shown on map
2. An exit route from freewys is not shown.
E.g., From I-270, should I exit from I-270, or change to I-55 then exit ?
3. The street (Rusty Road) is different from street listed on previous search
results page (South Lindberg (Lindbergh?).

Apple is much better:

Also good is the map from Pro-Retail.
