My sister moved 4 hours away from home at 22 to go to school. She knew absolutely no one and nothing of the area, other than what she'd seen in looking at the school she was going to attend and the apartment she'd be renting. The problem when she got settled in wasn't the money, or the lack of opportunity to do things...she lived 15 mins from Austin, TX...party central, plenty of shopping, the State Capital building, etc. However, it took quite a while to find people that she could hang out with...and it took several attempts to find QUALITY people to hang out with. After all, people aren't always what they first appear to be. She was lucky that our family could all take turns driving up to see her on our days off to give her some company and support. She was very low before she finally got settled with good people, and even still sometimes after.
I know you're not thinking about these things now, but when you get a little older and want to settle down and have children a place where there's "not much to do" will be so welcomed. And there is nothing like a good support system when things get a little less than ideal.
I am by no means saying don't move away from home...after all my sister met her husband while she was away and she learned a trade. However, when it was time to graduate and have babies, she moved back home to the comfort and safety of the small town life. If you do plan to move away, I agree with the previous posts, go somewhere you can go to school, even if its not a university--learn something like sonography (that's a shorter program). Good luck!
