Do your online research on each. Decide on what you are looking for. Go there for a visit, if you can, so you can see the town. Getting a fresh start might mean that you cut out the friends that got you into trouble, if that was the situation. It could be you need to change jobs - or you just got out of prison and want to start over.
Determine what it is that you want to change and put those goals on paper. Then you just need to research and make a plan on how to put your goals into action. Good luck.
