Province Size?

[bone_daddy]

Hmm, let's see. Typical infantry can move through two friendly no-terrain penalty provinces in a month. Assuming that a typical infantry unit can traverse 15 miles in one day, that would come to 450 miles in one month.

So a typical province should be about 225 miles across.

Of course, the 15 miles in one day might be high. If you factor in the time spent on making encampments and foraging, it could easily drop to 10 miles per day. This would reduce province size to 150 miles across.

Gandalf's probably right for counties in the Western U.S. In the eastern part of the country, it would be about five counties or so in size.
