Friend Daniel Chazin writes: "Today, I visited the massive Croton Dam in Westchester County. On the roadway across the dam, there is a plaque to commemorate its construction. I was appalled to discover that, in the fifth line, the word "height" is misspelled. One would think that in preparing such a lasting memorial, greater care would have been taken to ensure that all words were correctly spelled. I sure hope that greater care was used in the actual construction of the dam!"
