Pablo's favourite hobby is archery: he goes to the archery range regularly. The range has signs advising customers of the potential dangers, and prohibiting anyone from going beyond the firing line. On one particular visit to the range, Pablo was not firing his arrows well. A number of arrows fell well short of the target, landing not far from the firing line. Pablo did not want to pay for more arrows, so decided to walk out to retrieve the fallen arrows in close reach. While he was out in the field, he was hit in the head by another customer's arrow. This customer had fired a bad shot that went diagonally across the field rather than straight towards his target. Pablo has been unable to work because of his injuries and he wants to sue someone for his injuries. Please analyze whether you think he has a case.
