Yup, I delivered pizza for the Hut around the same time. Big ol' map of the area divided into sectors, each order listed which sector the address was in. I'd write directions on the back of the order slip, and go off into the night with nothing but a flashlight. First day I got a lecture by the manager on how to navigate by address and tell which side of the street a house was on, I learned more about navigating that day than in the entire rest of my life.
Sometimes I miss those days and wish I could be 19 and driving my tiny Honda Civic through the highlands again, listening to video game songs downloaded from OCRemix on my little MP3 player plugged into the car audio with a tape adapter.
Nope. Been there, done that, turned a relatively amicable breakup into a "you're a piece of shit and don't ever speak to me again" situation, ruining another friendship in the process. It's a horrible, horrible idea.
