Although it WOULD be cool to caddie in such a great event, the time, effort and money involved with getting over there would be too much of an opportunity cost for most people (so yeah, basically the winning bidder is mentally handicapped). Why not fly out to Vegas and gamble? I think you've got the same odds either way--an "Aussie hack" making the cut in the Open Championship or the no-limit tables in Vegas. Personally, I feel like this golfer is simply trying to cut his losses. "Hedging" if you will. With the bid up as high as it is already, he's pretty much covered his trip and a good portion of his liquor expenses. But I mean hey, if you can't get a sponsor to give you a lot of money, I guess putting a bid up on eBay is the way to go.

Obviously the dude has money to burn, but tt would be very cool to get inside the ropes on golf's grandest stage. Only in the US are we basically unaware that the rest of the world looks at The Open as the greatest championship in golf. How many memories do you think this guy will have by the end of this week? If I had that kind of bread, I'd do it too.

WHAT A GREAT OPPORTUNITY TO BE AT THE HOME OF GOLF, THIS GUY MAY GET SOME PRACTICE IN FOR ONE OF THE YANKS BAGS IN IRELAND NEXT YEAR WHEN EUROPE WIN THE RYDER CUP AGAIN !!!!

Agree with the sentiment of being inside the ropes at the home of golf. I too would pay a lot to do that (if I had it). Nearest I'll get is as a marshal at the senior british open next week.
As for the Ryder cup, with Woosnam as Captain the Europeans don't stand a chance I'm sorry to say.
