My tip while you are at the Latitude (or any other festival for that matter) is take a roll of extra large bin bags. You can use them for rubbish, as a survival bag if it gets a bit cold at night, as ground sheets, as an impromptu flag when yours blows away, as a mac to protect against the elements, as a dirty washing bag, as a rucksack cover and as a chair protector when you get in your car after living in mud for three days.
And be extra good - roll them up and reuse them for rubbish when you get home.
Latitude is in Suffolk. And mighty fine it is too...
When scoping out a field for a good camping spot - shaded/sunny, not too near the toilets etc - do make sure the spot you choose is not in a hollow. Remember, a lovely dry hollow in the sunshine is a pond waiting to happen in the rain. Unless you want your tent to become a water bed ...
