You have several options... first - beg your friend that spent many hours on at least one of the three previous ticket occasions attempting to secure their Olympic memories if you can join them! Two - check out a non-official ticket selling venue such as eBay or Craigslist.
Three - visit Vancouver2010.com and look at the following three options; Fan-to-Fan Marketplace, yes they're above face value, but they're genuine and guaranteed; Official Auctions, if you do the math the tickets are normally priced similar or even at cheaper prices than the Fan-to-Fan Marketplace prices; Day Of Ticket Releases, if there's time these will be online... but your better bet may be to show up early at the venue and keep your fingers crossed!
Hope you enjoy 2010!
