have you ever been lost in some random city (or country) where you don't know your way around and you have a deadline? this is a cheap and easy way to find your way where you need to go, by following a taxi.
Step 1: Getting the taxi
usually, if you are in a city, you can find a payphone, and a phone book. almost always, taxi services have their number in the book, for an easy way to reach them. call a taxi.
Step 2: What to tell the driver
when the taxi driver gets there, tell him you would be willing to pay him a modest amount if he would drive in front of you, and lead you to where ever you want to go.
Step 3: The payoff
when you get to your destination, pay the taxi driver a small amount for his troubles. this way, you get to your destination, while you couldn't get in a taxi and leave your car, but you end up at your destination in time. plus, think of all of the money you could save by doing it this way, rather than getting some gps!
