Keep a journal of your travels. You will sharpen your awareness of your surroundings and your writing skills. Reading your journal will bring back vivid memories of your vacation, which can often be used in essay assignments or just to help you relive that special time.
Get a map to follow your progress on the trip. It is fun to track your path along the highways and the map gives you a better idea of where you are and when you will reach your destination. You might even locate an interesting place to take your next rest stop. Information centers are great places to get new maps and other literature about the areas you plan to visit. The brochures you find make nifty additions to your travel scrapbook.
