Vacation time is precious. Most jobs don't even give vacation time anymore. They want you at work constantly, even if you're not being productive. They'd rather have a corpse there than not. It's like corporations survive off of the power of your soul. When people finally do get vacations they end up being at the same time everyone else is taking their vacation. What fun is that? I love Disneyland, but so does everyone else so the only time I go is when it's raining. You might get wet, but at least you can hit all the rides without lines.
The people depicted in this photo are all vacationing at the same time, which means jam packed traffic. Let's break it down. You get a week vacation so you drive for ten hours each way with the family. That's a full day of your vacation just traveling.
