Okay, I hadn't thought about the ruler thing. I should have. I knew there was distorion. Also, I had some fun playing with different projections, so thanks for that. Its actually very helpful.

But I am a little confused. I still need to measure between two points. How do I go about doing that with the scale that I have? Like, instead of the world map, if I am working with just that country, do I need a new guide?
