We actually helped out a fellow from the bush (a complete stranger) and he gave us spare tickets for the trap shooting (which Michael Diamond won) and the 3-day Equestrian event. We went into Homebush Bay a few times and just checked out what tickets were available and ended up getting to some really interesting events.
We were also lucky enough to go to one of the rehearsals for the Opening Ceremony as some of our family were involved with the Pyrotechnics. Andrew was part of the huge team from Foti Fireworks and was involved in both the Opening and Closing Ceremonies for the Games.
Friends of ours hosted some of the Weightlifting team from Belarus and had an amazing time - even though there was a few communication issues:D
The Volunteers were really wonderful.
