Dave...I just re-read Matts post. I didn't see anything about the Tiger worlds surpassing SF in attendance. (I expect it will). Matt simply explained how these conflicts happen particularly with a world event and the advanced planning required.
As for your HCA F'up...The suggestion that a Tiger world championship regatta should change dates that work for them to avoid a conflict with a local F18 regatta 2500 miles away is ridiculous.
