Random Thought

Last night while feeding Cortland at around 3 am I finally thought of something you would use geometry for in a real life. You could use it to find water lines buried in the yard. Yes? Or you could just use a buried treasure map. But the guy that ran the pipes would have had to make one at the time of pipe burial and I haven't met a pipe burier yet that has enough imagination or the time to draw a detailed map with pictures and clues and riddles all over it.
