It doesn't matter if you're a tourist or a local, in a car or on foot. If you try to navigate a city using only your brains and eyes but no map, you're going to get lost. I guarantee it. You'll end up in a bad part of town trading your spouse for a sack of rock and you'll think to yourself, "How did this happen? An hour ago we were on our way to the aquarium. Now I'm addicted to crack. How?!"
I'll tell you how. You didn't look at your map. Now you're lost. That goes for real life as well as video game life. Take a look at the video below and watch as a fun day of racing turns into a no map nightmare.
Ok, so maybe that wasn't as bad as hookering your spouse for crack but still, we feel good we warned you. Use a map.
