I fly in Southern Ontario, where we're bounded by the Great Lakes. My navigation is simple... if I hit a big lake, "home" is the other way! We're also up on a very large plateau, so if we drop off the top, turn around (No turn points out that way).

I'm being silly, of course. I use GPS and carry a letter-size sheet with the turn-points and major objects on it for most navigation, plus the VNC is tucked in by my hip.
