I am having trouble deciding whether or not to go far away for college? Help please!!?

I am a honor roll student and am 11th in my graduating cl of 135 students. I live in a small town in rural machusetts and have always grown up with not too many people in my school. Now that I am applying to college and getting my acceptances I dont know where I want to go. I applied to 5 schools: UM Amherst, UM Lowell, University of Rhode Island, Clemson University and CU Boulder. Initially I had it in my mind that I wanted to stay close to home, and I applied to Clemson and Boulder only because I really liked the campuses and liked their programs. Now that I have gotten accepted to Boulder, however, I have been researching more and feel like I really want to move out west. I feel like I need to get away from new england because I want to experience what the rest of the country has to offer, and i need a new setting. I do not like the campuses of Um Lowell or URI, (i only applied there as backups), so the only close to home school is Um Amherst. I do like the campus, but I feel as though I would have a better time in Boulder... and as for Clemson I have not been accepted yet but I am not sure if I want to go there. However, now that I have my heart set on Boulder, I realized that I can't really afford it. Its roughly 40,000 a year, and they havent given me any money to go there, meaning I'm going to have to apply for tons of scholarships if i want to go. Therefore, I was looking into cheaper schools out west, and found Arizona State University in Tempe and I feel like it is a perfect match. Its cheap enough and has everything I want, however now my parents dont feel like they want to let me go. They keep telling me all these reasons why I should stay in Mass, however I really want to go to Arizona. Does anyone have any suggestions?
