An excellent guide to interesting road bike trails in IL. The routes have been created and tested by the author, so the information in this book isn't something you can get from just going to a trail, forest preserve, or state park website. There are turn-by-turn instructions as well as information on local attractions, restaurants, highway and railway crossings, restrooms, and bike shops. This is a really great resource, but I will recommend double checking all of the information online before going for a ride. ( )
