Why didn't I think of this?

Investment banker Michael Mahan spent nearly $25,000 buying tickets for two games against the San Francisco Giants at Dodger Stadium next month.

He figured it was a worthwhile investment, because Bonds' 700th home run ball will fetch a much higher price.

But the Giants' slugger has already hit his 699th home run and is likely to reach the milestone any day now. So Mahan is reselling the tickets -- at a considerable profit.
