I could have used one earlier. I had someone telling about all the different campground sites and he kept pausing for what felt like an eternity (I was at work so the time he spent pausing trying to think of where it was is time out of my day I could have been using to better organize my desk) to figure out exactly where the location was. I could have easily looked up the locations and he could have told me all about it, I could have made nice clean notes, etc. Instead I used two pieces of paper to write down a jumbled mess, then transferred that to one clean piece of paper and when I get home I'll have to then transfer that to something else so it doesn't get lost before we can check into these places. Lol.
