atlcomedy is exactly right. It played hell with my schedule, & I'll be 2 months getting caught up. It can be worse though, Federal Jury Duty is q 2 month term, but they generally give a weeks notice before you are required to report, so you can sort of carry on as usual. Just can't really plan anything more than a week out.
Grand Jury is really a bitch. Three months, and you are absolutely at the mercy of the County Attorney, who can decide to convene the Jury anytime he wishes.
