"Man, you thought latitude and longitude was rough, just check out this declination stuff!
I'm sorry to be the one to tell you that your compass doesn't work quite right. It doesn't really point to the north pole or the south pole.
Not only that, next year it will point someplace different than it does this year! And, someday it may be completely backwards!"
Maybe this is why I can't find my way!!
