One other maddening quirk I forgot to mention: address always count up
from the baselines, so if a road is U-shaped, with two legs heading
north, and an eqast-west connector, addresses will count upward along
both N-S legs *simultaneously* - xNyy0 and xNyy5 might be on one leg,
xNyy4 and xNyy4 might be on the other - so you get the absurdly
hilarious situation of seemingly adjacent buildings actually being a
"block" apart in parallel, where that block might 1/4 or 1/2 mile.

Lake County, IL uses a similar system, but with the directional letter
removed. Parts of Wisconsin use *two* directionals, of the form
NxxWyyy, on similar grids.

Ah, rural Chicago addresses.

Kane and DuPage counties use an arcane system based on the number of miles
you are from State & Madison in Chicago. In this case, you in the 16th mile
west of State. Within a given mile, addresses increase from 000 to 999,
inclusive.

What's truly maddening is that this is only for unincorporated areas, and a
few incorporated municipalities that never created their own grids, so wild
jumps like you describe usually involve a village/city limit.

I happen to live in Kane County, so I'm used to this weirdness by now.

http://www.burr-ridge.gov/E-Services/GIS/GIS.html shows that they don't 
appear only on the frontage roads, but are all over the area. Random 
guess: could they be from an old rural free delivery route?
