Trek Farley 9.6. Mostly sunny, warm! - got up into the high 60's, probably a record for late February, pretty brisk South winds @ 13-14 mph but not much of a factor in the woods. I love riding at Deer Grove except for some of the really muddy parts... but it appears the Cook County Park District is seriously fixing what ails this place. Not done but they're making some great progress with new well done gravel repair and even total gravel repaves in sections. Did the usual both direction loops for a somewhat longer ride than the usual. Temps were so nice, I changed into a short sleeve jersey in the parking lot. I saw quite a few cyclists and lots of hikers and dog walkers. Also, 3 locations for open Port-a-johns. First ride here on the new fat bike and it's perfect for riding these trails. Eleven days in a row riding and the legs feel great!
