My Shave Avenue letterbox is missing. But unlike several other letterboxes that have disappeared leaving me with questions of, Was it an animal? Park staff? An unscrupulous letterboxer collecting hand-carved stamps?, there’s no mystery left to solve in this case. It rode away with the train it was planted on. While sad for my fellow letterboxers, I’m happy for the Alta Vista neighborhood residents who have been trying for a year and a half to get the old boxcars removed.
