Driving for Dollars Mapping software?

[Scott Nolan]

I've been doing enough Driving for Dollars that it's beginning to be a little difficult to remember whether I've already driven any given neighborhood.  What I wanted to do was get a map book of my county and just highlight the streets I'd already driven.

Y'see, kids, before the rise of cell phones, maps were printed on dead trees. And they didn't talk to you. Usually, the cell phone is easier, but using a highlighter on it makes the screen all yucky and voids the warranty.

So. Does anyone know of a good app that can help me mark off where I've been?

Thanks,

Scott
