So, is anyone in Harris County getting an unusual number of jury summons?

When I first registered to vote, I think I averaged one summons every 3 years. I've just received what is my 3rd summons in 13 months (it's my 4th in 22 months). I don't mean to whine; unlike a lot of people I don't look to "get out of" jury duty. I don't hold it against the state that I spent 7 long days listening to fascinating mold and renters' insurance testimony just a year ago. Well, not much anyway.

Has the compliance rate dropped precipitously? Have I got "Sucker" tattooed on my forehead? Is this one of those weird, "when it's truly random you get things like this" things? Shall I expect to be getting these things every 4-6 months?
