Went for a 10 mi jog at Waterfall Glen in Lemont, IL (which is a giant loop). There’s a bridge that’s been out for a few weeks, and the detour you have to take it not clear. Saw a number of confused runners standing around or even turning back where the trail was closed off. Told them all to follow me for the correct detour. Felt good to help out my fellow runners and lead them through one of my favorite areas. Sunny, about 31°F, nice day!
