** 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!
