A couple of readers have correctly pointed out an error in my Sunday column about my trip to Iowa.

(To see it, click here) At the end, I noted that one of the messages on the wall in the basement was from my Uncle Roland - apparently left in 1934 - that read "Roly, age 14, Bode, IA. 50519"

That is what you call an anachronism as zip codes didn't go into effect until 1963. I went back and checked the video. The message actually reads "Roly, age 14, Bode, IA, P.O. Box 222."

I'm not sure how I messed that up. My notes include a mention of the silver Bode water tower near the public school. The tower reads "Bode, 50519." I must have somehow merged the two.

What's interesting is that I didn't know my father's address in Bode, which made it difficult to find his house. Before we went there, I looked for the street address among the family letters, but the only letters I could find simply said "The family of Oscar T. Gullixson, Bode, Iowa."

There was no need for an address, I guess. Everybody knew where they lived.

Anyway, thank you to the readers who pointed out the mistake.
