Cloudy, warm, humid but not overly hot start for a large, great group (16) ride from KHMS through Oswego, Yorkville and Plano. SW winds were mild to start but increased over time. Jeff L corralled the fast group while I stayed back for most of the others. All stayed together for the most part down to Oswego, but began to separate after crossing IL71 on Minkler. Wally, Rob, Greg and I stopped at the Speedway in Oswego for extra water. Mary MB rode on and detoured home before we were able to catch up. Rob dropped his chain prior to the punchy hill on Hale and emitted language that I cannot reproduce here. Came across John and Heather in Plano and they left just as we rolled in. The heat, sun and winds all increased on the final stretch emptying our tanks. Renee, Rob and I grabbed a quick lunch at Obscurity.
