May 15th marked 100 years of this historic event, and I would like to thank Storm for hosting his Monday Mail Runs with us. He provided loads of wonderful information with a greatly themed group flight series across the United States, following the same routes very closely. I learned a lot from these events, and grew an interest is something I probably wouldn't have looked twice at otherwise.
Here is a video recently posted by AOPA showing some of the history, and showing how a few people are keeping early mail run energy alive.
