I was at the Madison Square Garden NetJet Showdown on March 10th to see Federer vs. Sampras and it was great! They are both quite the showmen and were very friendly after the match at the press conference/after-party. I just was sent the link to buy the DVD online: http://www.showdowndvd.com. It was definitely worth a watch or two and there were some very memorable moments!
Check it out!
