Taking a trip across the country can be very difficult to prepare for, for multiple reasons. First, if you are going to travel that far you need to make your trip worthwhile. More specifically you should try and stay for an extended amount of time. Also, if you are going to be there for a while you need to pack more things to get you through. Mostly you will need more clothes. It is also very difficult to decide which clothes to take when you are traveling to a place that you have never been because you do not know what the weather will be like.
