Taking their cue from Indiana Jones, a group of charity minded industry folk have got together to launch the "Search For Your City" treasure hunt which is taking place in London on Saturday July 5th.

We all know there's nothing the travel industry likes better than a bit of gratuitous dressing up, so it's time for the guys to fish out the trilby hats and whips the girls to put on the rather fetching Russian femme fatal military uniforms - all for a good cause, naturally.

Everyone meets up at The RS Hispaniola on Victoria Embankment at 12:00 noon and sets off across the city looking for the vital clues. When you find them you take a picture with your mobile phone to prove you've been there.

The team behind the Search Your City charity treasure hunt are Ian Fyfe from Bateaux London; Heather Cameron from the Leisure Pass Group; Rob Way from Morris Visitor Publications; Katherine Grimster from the Hard Rock Café; and Amanda Truman from Leisure Pass Group among others.

There are some top prizes and the £20 team entry fee (or £10 per person) goes to the Children's Country Holidays Fund.  To register for the hunt go to www.justgiving.com/searchyourcity.
