Fav Places in the US

I'm going away this weekend for the first time in years and years and years! I am so excited about it! I am new to traveling - I can count on one hand how many states I've been to and have never been on an airplane lol. So, I was just wondering, where are your favorite places to visit in the US? Whether, it's a city, a place, a park, or just a whole state, let me know where and why, so I can expand my list!
