Abandoned Funfair Treasure Escape

This funfair once used to be a very popular recreation spot for all the people of the area. In fact, people from far off places used to come to the fair. However, the funfair has been abandoned for a decade now. It has become a secret hiding place for some thieves and robbers. One day as you were passing by the abandoned funfair you noticed a group of robbers enter the area with box full of treasure. You could not see where exactly they hid the treasure. You have now come back to the same place after some days with the intention of finding the treasure. With no one around this is your best opportunity to go in and look for it.
