At long last, a map is available showing the cross-country skiing and snowmobile trail systems across Cook County. Printed on weather-proof paper, the product contains an overall Cook County map, as well as large inset maps showing individual trail systems. Included are trails designated for snowshoeing and winter bicycling. Some of the trails are also routes for sled dog races, although this use is not marked on the map. The full-color map is detailed and, if you study the legend, easy to read. It’s a great addition to the day pack of any winter adventurer.
