Isnt' the Air and Sea show on Ft. Lauderdale beach soon? They just had it here in Tampa. I live about 2 miles from MacDill A.F.B. and they were all over the place.
Are you sure they were F-15s or were they F14 Tomcats? They look very similar and can be confused when seeing them from a distance. If they were painted yellow and blue - The Navy Blue Angels.
