Trek Farley 9.6. Just a gorgeous Spring day - Mostly sunny with beautiful high clouds that seemed to change whatever direction you looked. Warm - in the 70's, high in the low 80's but comfortable with moderate humidity, winds were fairly mild and variable. Lot's of people out - hikers and cyclists. This has always been one of my favorite rides, hits 5-6 DuPage Forest Preserves, all connected by a great trails system. Start at Warrenville Grove, down to McDowell Grove, back up to Blackwell and McKee Marsh, over through St James Farm, a bit of the Prairie Path into Herrick Lake. On a faster bike I'd have also covered Danada FP, but this route was perfect for the fat bike: great mix of Limestone, grass, woodland trails and even some singletrack here and there. Trails were pretty dry and the grass was soft. I carried the backpack hydration, good call for a 3 hour warm weather ride.
