For anyone interested in what your county government does for you, I published the Winnebago County Personal Function Review documents on my County County Board Website: www.winnebago17.org.
Also, I put together a smaller overview of 71 Things Your County Does (why 71? I wanted to keep it to 4 pages). I did not include some obvious ones, such as roads.
If you want a larger read, the full 23 page program overview is here.
