knobbygb, you're probably correct about how to penetrate the ADIZ (and check the warning area status!). I was just told by one of these experts in baseballs caps that hang around FBOs that I mustn't fly through there, and as I hadn't planned to anyway, didn't check up on why not! Maybe one problem is maintaining contact with Miami Center - they don't seem to hear you from 2000ft (or maybe too busy and just ignore the little guys).
Great site for checking fuel prices and FBO reviews is
