Example:
Me and my friends learned that geocaches can be in the most unexpected places like a magnet upside down under a bench posing as a bolt. It took us 30 minutes to solve the geocache because it was our first time. When we got to the location and started searching for the geocache we were full of alacrity, but after 28 minutes we couldn't find it and we searched every where we could think of like in the trees, in the, park, on the ground, in the tiny pond, and in the grass. We decided to take a break on a bench when it finally happened one of my friends noticed that one of the bolt on the bottom right of the bench was unusually large. She took a closer look and saw a geocache symbol on it. She had found the geocache under a bench! We also found the log under the bench and signed it. When we finished we put the log and the "bolt" back and went onto the next geocache. We were very excited about the fact that we had just solved and found our first geocache.
