Where do you live? Oh, I am _perfectly_ willing to pay up... I lost, fair and square. It'd be more like $1500 I think, for airfare for two from LA -> Raleigh NC (I live in Greenville NC), hotel, dinner & drinks. I can't give away too many details, but Will has something up his sleeve, and may make me "pay up" in another way. :) Totally his call... -- James > >anthony
