Seven. A picture perfect day, felt like Fall in late September. Partly cloudy, cool and comfortable with decreasing humidity, mild to moderate Northerly winds @ 8 mph. Solo ride up the Millenium trail on some great (and not so great) Lake County trails. Started on the Des Plaines River Trail in Libertyville just below Independence Grove and travelled through Liberty Prairie, Almond Marsh, Grays Lake, Rollins Savanna, Fourth Lake and finally McDonald Woods. Bit of a headwind going North so the trip back South was pretty nice. Note for future rides: the wood chip loop in McDonald Woods is not for bikes - I rode it anyway but it's too soggy and hard to ride. Good bit of climbing on the ride but nothing too difficult. ~1,300 ft ascending. Nice long ride, good recovery after yesterday's hard road effort. Stopped at Mickey Finn's Brewery in Libertyville for rehydration, first time there.
