If you are a sex offender they will hook you with an anklet that is basically like a GPS system. It is really expensive, so in most cases, the Department of Corrections assigns an officer to you and you have to give him/her a weekly schedule. You are allowed to got to work, school, grocery shopping, etc. In my case, my PO is pretty cool with me b/c she deals with a bunch of scumbags all day and it is obvious that I do not fit in with these people, so she treats me like a human being. She lets me toss the pigskin, run stairs, and go to the library...these are things that normally she does not let people do. House arrest in no joke. I have gone out partying a couple of times, but she has shown up at two in the morning before and also, she sometimes shows up to the house with a breathalizer. If you are >21, you cannot blow >.08, if you are <21 and blow even a .01, you are violated. I can't wait until January 16.
