Online there is a very good booklet at http://www.dot.state.il.us/bikemap/litlist.htm (look for the pdf about safe bicycling in Illinois). It has all kinds of stuff including suggestions for dealing with police who may not know the laws (and tell you you shouldn't be doing something you should be doing or the other way around). The Chicago Bicycling Federation is, I believe, behind that particular tome.

Good ROllings on your adventures... yea, try to find cmpany! THen the drivers might think there's a movement...
