Grand Jury Duty anyone?

I've been selected to do Grand Jury this month. It's a bit different than trial jury in that we were selected by drawing out of a hat and most of us stayed. We are there for a month time and our duty is to determine whether or not a case has enough evidence to go to trial. There are three groups of 7 people (one group for each day; Tues, Wed, and Thurs). We went through 4 cases today but average is usually around 8 or so. It's very interesting to find out what goes on behind closed doors in your area. Can't say any more than that. Overall, I actually don't mind it at all.
