You and your family are at the best amusement park ever! You have been on so many great rides, bought souvenirs in the gift shop, and have eaten all the junk food your stomach can handle! What a great day it has been. Now that the day is over and the park will be closing soon, you must make the long trip through the park and back to your car in the huge parking lot. You hope your legs will hang in there a few more minutes to get you to the car. Just as you begin the seemingly endless walk to your car, your mom looks around in a panic! She has dropped her cell phone somewhere and remembers she had it about 45 minutes ago. Now you all must retrace your steps and go back to all the places you’ve been in the last 45 minutes, but you must hurry! The park is closing soon. Work together to solve the puzzles, open the locks and earn a prize! (Grades 6-12)
