The story has two versions - at least - about Truman's middle initial. Some say it has no period after it, and others say it does. The most recent scholarship that I've read says there is a period, and I've read that his tombstone also has a period after the S. Truman served just 82 days as FDR's vice-presidet, when Roosevelt passed away. Truman assumed office and was immediately faced with the decision to drop the first atomic bomb in Word War II.
Enjoy the cache. Park carefully. Be safe. Have fun!
** A note from IowaChupacabra: Hello! I am attempting to maintain Blue Grass Tom’s geocaches. Have fun as you travel and explore up and down these Iowa back country roads to find the geocaches in this series. As you do so, if you happen upon a wet log, torn bag, or cracked/damaged/missing container, and graciously make the choice to add/replace paper/bag or change out/replace a container, I would certainly appreciate it and Thank You for the help. I attempt to make a run through the area every few months to fix the problems noted in the logs, but there’s always something! Thank You!
