The wandering campsite wardens and security teams are looking out for dangerous fires, accidents and risky situations - please help them and utilise them. If you are unlucky enough to be a victim of crime, report it to the Police HQ, who can give you a crime record for insurance purposes.
Tents are very vulnerable, even zipped up.
If you didn't get one from the Gate, go to any Info Point or ask any Police offer. Postcode your equipment and valuables and be inventive about hiding your money. Spread it around. Tag your keys with the phone number of a relative or friend - not your own phone number. Make use of the free 24 hour Property Lock-Ups which are prominent around the site.
