You may not separate, split up, or leave players behind. Half of your team cannot go around the block, and one or two players cannot run ahead of their teammates. Your team will be required to travel at a pace all of you agree upon. Make sure you're all in agreement on this before the hunt starts. Each team should choose a name for itself, the more inventive the better.
Every player receives a detailed map of the hunt area, and a set of clues.
When you find them, write them on the score sheet to prove you solved the clue. It is best to search systematically. In the past, people have missed letters by quickly shining their flashlights over an area in a cursory manner. The letters adhere best to smooth surfaces, and I attempt to avoid placing them on private property. It's to your advantage not to let other teams in the area know if and where you've located the letters.
