There's nothing like having a full meal while cruising along V3 up to SAV, the PA44 backseat will hold a lot of food, who needs ballast bags, just pack the thing with food. (Just remember that if you bring along sealed packets of food, let's say ranch dressing just for example, that they tend to expand and explode at altitude.)
Ahhh the good times.
As for call signs, I refuse to fly anywhere that I can't use one, it makes me feel important.
