Hello Michael, where do you want to go today?

I've always scoffed at in-car navigation systems.There's plenty of stories about accidents caused by folks blindly following the instructions. The unit that G's Mom has refuses to recognize the existence of the Kerby exit from the Fremont Bridge, sending her up 5 North all the way to the Alberta exit when she tries to visit.
I've always been a map person, I learn the lay of the land quickly when I visit a new city. I can't help it, its just what I do. After seven years of driving, biking, and walking around Portland, I have a pretty detailed map of the metro area in my head. Since I started riding my heavy-ass old bike more often, I find I pay more attention to the topography, learning the most efficient path between home and work with the least incline.
This is the only SatNav unit I'd ever put up with, just for the novelty. Otherwise, I'm the navigator, dammit!
