Fair enough.  I think the towns out-weigh the long roads though, and 
even if you don't have grid iron streets, then every t-junction, 
crossroads, roundabout etc contributes more lines than roads.

That's the way I see it on screen grabs like this one anyway....

I'll see if they're easy stats to pull out of the database anyway, then 
we can keep track.
