Hey, a pretty ad hominem post for a first timer. But then you are taking a position somewhat preposterous on its face...
Reminds me of the lawyer's stratagem "When the law is against you, argue the facts. When the facts are against you, argue the law. When both are against you, call the other lawyer names."
I dont think you can call Daves post ad hominem because he is the owner and skipper of the boat that won the 1988 race and placed 3rd overall in 1990 (beating every other boat in his class on elapsed
But, it is par for the course around here to insult without consideration.
So he has been there and done that. No need to argue with fact.
