Hidden Cash treasure hunt hits London
A millionaire who has been hiding envelopes of cash in cities around the US has announced that he will take his treasure hunt to London this weekend. 20 envelopes stuffed with £100 cash will be hidden around one of London's parks, and then he will tweet clues on @HiddenCash to help people find them. The winners are then encouraged to post pictures to the Twitter feed.
So why is he doing this, and can you cash in?%VIRTUAL-SkimlinksPromo%
