I love traveling too! The only place I've been outside of the United States is Mexico, but I have been to some cool places.
One of the most interesting places I've been is New York. The City has tons of places to go and things to do or see- I highly reccomend a trip to New York City if you havn't been. If you do go, do not stay in the Portland Square Inn! Make sure you visit Central Park, and if you have time to see a musical on Broadway, Phantom of the Opera is great.
My favorite place is California. California has something for everyone- mountains, beaches, deserts, and forests. The Central Coast region is especially nice. If you want to see cute little coastal towns, visit the Five Cities (Grover Beach, Pismo Beach, Shell Beach, Arroyo Grande, Oceano, Nipomo, and Avila Beach), and Monteray Bay.
