Guys there's a million threads on this subject. I can tell you for sure that they don't test for gear in any state, it's just too expensive, but if you are on probation for a gear related offense then yes they will test you for gear. And even if your not on probation for AS related offense, your PO can test you for AS if he wants to. They can basicly do anything they want.
Just stay on your PO's good side and don't piss him off is the best advice I can give you guys.
Goodluck,
