STLToday has a very moving story about Raynard Nebbitt, whom you may not know by name. On the other hand, if you travel I-44 at all regularly, you know him by sight. He is the man who travels every day to the overpass on Rock Hill Rd., flagging down trucks to honk their horns. He has a mental disability, and this overpass is his daily routine, his daily task-- or, if you will, his daily apostolate. Since it seems I have a contractual obligation to drive to the Dance Center of Kirkwood 14 times a week, I simply refer to him as "Maddie's friend".
Anyhoo, it seems that due to a recent physical disability of his sister (who had been able to work and support them both), he was forced to move to the city, where his daily bike ride now takes over an hour each way.
The quote in the above headline comes from a commenter at the STLToday story. It is a very worthy read.
