As a kid we went camping near a reservoir and it rained real hard through a couple of nights. One of those nights there was some serious lightning. The loudest lightning crack I ever heard scared the shit out of me and woke everyone in the tent up, but we all stayed quiet. I was terrified. It had to of hit the ground relatively close. I thought it was going to hit again and get us. Thankfully it calmed down after that strike and sometime later I fell back to sleep.
