This is more towards urban errands, but I have an app on my iPhone called 'AroundMe'. Get free app for finding a home or business. In any regards, I have to be careful to make sure it is on the auto feature because it also has a walking feature. This walking feature avoids freeways and generally takes a more direct approach, 'as the crow flys'.

This hasn't much to do with this thread but its critical when using any technology that the settings are correct.
