Monaco Grand Prix - Formula 1 race. 200,000 people plus mega yachts all surrounding a race track in middle of city - rain at start of race, delay 1 hr but it went off well and very exciting though difficult to see what cars are the leaders as they move so fast and you cant see the numbers. But Ferrari was 1&2 to start but Red Bull made the better tire change decision and won the race with Ferrari second.
