When America was first being formed, it was decided that the states should have the right to create their own laws. To this day, the same principle is true. Unfortunately though, this creates a problem for citizens today. That's because we are a very mobile society now, crossing from one state to another. When we visit these other states, we have to abide by their laws. But because not all laws are worded the same, you might find yourself trying to assert rights you might not have.
