That's a great idea, if only for the discounts. But I don't think we could do that in CA. You supposedly must get a CA license within ten days of arrival which I did. However, it was a long time before I registered my car here (WI kept renewing it by mail) and Farmers was willing to issue insurance then on an out of state vehicle. I will look into this, as I have un-registered to vote and the property tax exemption for being a state resident is teensy. However, I do take dirt-cheap community college classes at resident rates.
Did you surrender your Florida DL? You must do that to obtain a CA license.
