After Milwaukee it was great circle to Dawson Creek. I found it somewhat
aggravating to try to plot the course enough to even find out what charts to buy. One
cannot simply "draw a straight line" on a big chart.

The easiest and quickest way to find a great circle is to stretch a
piece of thread between the two points on a globe. I "snap" the
thread a couple of times to overcome friction, and of course the
larger the globe, the more accurate the plot.

If you don't own a globe, the nearest library probably has one.
