Be careful, and pay close attention to the signs when leaving MIA. There are a couple of abrupt lane changes required to make sure you get to the highway. Miss one, and it becomes easy to end up in a less-than-desirable neighborhood.
The last time I was down there (go there once or twice a year), I did not have a carry permit. I don't think I even had a piece in my vehicle. If you want Dad to bring one, just have him leave it secured in the vehicle, preferably in the trunk if there is one. Then, discreetly move it to the passenger compartment and into a position within the limits of the law when you return to the vehicle. Remember that, while making the move from the trunk to the passenger compartment, you would technically be in violation of the CCW/CCF law for a moment or two. Discretion is a must!
