For those of you who live in the Orange County/Riverside area (SoCal), where do you put your FasTrac transponder?

I'm not willing to put it on the windshield or dash - and the antenna array doesn't "see" it in the sunglass holder (between the radio and the climate controls). Currently, I throw it on the passenger seat when I go through the array, but would love a better choice.
