DC is amazing. I went last summer with my Advanced Placement American history class. If possible don't drive unless you have to..take the subway and if your driving to the subway station get there early to find parking. DC subways are really nice and clean. I'm like you in fact our whole group was..we we're all quite amazed at the subway because most of us had never been on one let alone seen one up close and personal. Going to the District of Columbia from Arkansas was like taking a rocket to the moon. I had never seen a skyscraper or been in a really big city. I hope you enjoy your trip and if you want to know some awesome places to visit just message me!!
