Via the Daily Telegraph:

Families hoping to enjoy a day out at next year’s Olympic Games will find they are very limited about what they can bring into any of the venues. Every bag will be X-rayed in a series of security checks as stringent as those at airports.
People booking tickets, which went on sale this week, have to sign a terms and conditions document, which runs to 7,350 words, published by the London Organising Committee of the Olympic Games (Locog).This list of rules and regulations makes clear that the following items are banned: “Food, alcoholic and non-alcoholic beverages, liquids in containers of greater than 100ml in size, umbrellas, horns, whistles, drums, rattles, musical instruments, or any other devices that in the opinion of Locog may disturb a session (including mobile telephones), flasks, Thermoses and in general any material that Locog may deem dangerous or that may cause damage or disruption to a session.”
The conditions suggest that anyone wanting to bring a picnic to a venue – a tradition that many British sports fans indulge in at Lord’s Cricket Ground or while watching the tennis at Wimbledon – will find themselves banned from entry. Mobile phones, which most people now find invaluable, are also not allowed.
A spokesman for Locog said the organisers wanted spectators “to have lots of fun”…
