F16's aren't invited Dave?

You're killing me brother.
Of course the F16 fleet is invited Karl, why you gotta be like that? The F18's are my world you know that. And when I join the A cat fleet they will be my world... and I have no doubt they will say... crap! There goes the neighborhood! That's right Mr. Moss (they are a bit formal in that fleet) the clock is ticking for you buddy! Yeah go ahead and reply I dare you... pussy!
If, by "formal", you mean establishing a strict schedule for sailing, jacuzzi, strip club while also making sure there is enough stock to not run out of rum for the evening, then yes, a-catters are quite formal.
