We were sitting at the window at Carl's Jr., right next to the fence when all at once the noise became louder and louder, like an enormous dump truck dumping a load of rocks. It went on and on and became even louder, we didn't have any idea what was going on but suddenly noticed the reflection in the window of a building collapsing right beside us!!! You can't even begin to imagine how funny our reaction was, we just cracked up. That had to be the last thing we expected to happen! I guess we'll never pass a Carl's Jr. without smiling.
