Encounter Table - column shifting

I have been sort of quiet this week, in part because I have been working on this encounter table idea.  The concept is that your encounter table for a certain large region includes all terrain types, and then there are column shifts from right to left or left to right to show changes in conditions, such as bad weather, or other situations where a normally safe area becomes more dangerous, or a dangerous area becomes more safe.

Ideally there would be a few more columns to show the differences between say, city and dangerous city, but I did not have 16 more ideas at this time!  I also used 3d6 to make it more regular, and repeated entries to make it even more so.  So there are lots of "peasant" entries. (roll on sub table).  In addition, my entries are more naturalistic than fantastic, and there is very little on there which is straight magical... which I think fits the setting.

As always the excellent silhouettes are from Telecanter.

Any thoughts?

Also, a welcome to New Big Dragon, who has an interesting looking RPG blog. (which I am trying to resist reading before publishing this post)
