Mostly sunny, cool but comfortable in the low 50's, 5-8 mph SW winds. First half of the ride was pleasant but trail conditions suffered the farther I went South. This is the first or Southern part of the Des Plaines River Trail and if you're looking for a part to skip, this is it. The trail below Rosemont (South of Catherine Chevalier Woods) is in horrendous shape, mostly dirt and mud with countless felled trees over the path, dangerous road crossings and flooded culverts where they even exist. I won't do this section again. Similar to the Chicago River Trail, the areas in poor neighborhoods are poorly maintained. As you head North into more affluent areas, the trails and parks improve. It's a shame that Cook County Forest Preserve doesn't maintain their parks the same everywhere. 2 or 3 culverts were completely flooded or full of mud so I was forced to take the overpass route across 4 lane busy highways with no lights, curb breaks or crossings.
