That, to me, is an unrealistic way to fly an airplane. Who descends to below 1,200 agl 10 or more nm away from the airport to skirt below the class C?
How about flying in South Florida, along the beach, from Palm Beach to the Florida Keys. Great Views and below 1000AGL(which is the same as MSL everywhere in SFL) you miss almost everybodys airspace except Pompano(PMP) and Ft Lauderdale(FLL) [attachment]SFL.png[/attachment]And the satellites around FLL are not completely owned by the Towers
P.s. All of the Class D airports around KFLL are also not as you say! HWO, FXE, OPF, and PMP all have given up their airspace above 1500 to MIA APPCH. So you will have to call appch for those Class D airports for entry at or abv 2000
