Re: Re: True North vs Magnetic



I was confused about this as well and asked this question a while back on
this reflector.  I received a bunch of great answers, but while I was
browsing the web one day, I came across this site that I thought I'd pass
along:

http://vader.castles.com/tomhyatt/magvar1.gif

It has a map of the US showing the lines of magnetic declination dated 1990.
