Farley 9.6. Gorgeous day,c Cold - 18 at the start, up into the low 30s by rides end, but very bright & sunny so starting to thaw over the last hour or so, West winds @ 5-10mph. Parked and started at Blackwell Forest Preserve in Warrenville, rode through McKee Marsh, down through McDowell Grove Forest Preserve, then back through Warrenville Grove to the starting point. I only saw one other rider and just a few hikers. I ended up cutting about 6 miles off the planned total as thaw was setting in and it was getting muddy and messy. Limestone trails were pretty much a mess, mostly due to worker truck traffic, and idiots riding skinny tires in the muck over the last week or so - fat bike is the way to go when it's like this. Stopped at Pub 56 for lunch, then stopped at Penrose for a couple of pops.
