As I rode on the route out to the far end of my route when I was about to turn around I saw a guy in the parking lot of the recreation area repairing his bicycle. He was sitting on the curb with the bike turned upside down in front of him. It looked like he had been there a while. When I came back thru about 10 minutes later he was still working on it. I pulled over to where he was. He had pulled the chain apart for some reason. He had a big chain tool. The chain was broken apart but he had removed the whole link and the pin out of the link. I told him it was nearly impossible to reset the pin. He needed to take a bit more of the chain off and PARTIALLY remove the pin. I finished the job in about 3 minutes with the chain together. He said he only spoke french but appreciate my help. He was a big Black man from an African country I assume. He couldn't tell me much, but I felt good helping a fellow cyclist
