A scheme has been set up in Bedfordshire to try and make a local beauty spot safer.

Two years ago three young children drowned at the Blue Lagoon near Arlesey when the car they were travelling in went over the cliff edge.
Safety barriers were put up, but they have been repeatedly vandalised.
Now police and people living nearby have started Lagoon Watch to try and stop the damage.
In 2002 unqualified driver Courtney Barker, 23, was convicted of triple manslaughter after the deaths of the three children.
Barker was at the wheel when the car fell 30 feet into the Blue Lagoon lake.
Imran Khan, aged six, Aaron Khan, five, and Sharla Blair, three, were trapped in the back seat and died in the incident in July 2001.
