This is the 3rd letterbox of the series. We start near the parking lot. I spy a pole with a sign. It mentions Tree City USA _ years. After you make a note of the number, go down the path. At the fork turn left. Walk for a short bit. On your right you will see a playground. There are green benches around the perimeter of the playground. Take note of how many you see. As you continue again down the path, keep the baseball field to your right and you will see a sign on a pole with a red "no". There are _ words on the sign. Continue along the path until you have circled the ball field. There will be a building behind home plate with a plaque dedicated to Joe Forbes Field. Make a note of the dedication date. Keep moving down the path and continue thru the woods. When you exit the woods, turn left at the intersection. You notice a yellow truck. How many vents do you see on the side of the engine hood of the truck? They will be visible from the path. Next you will see a train. How many tires are on the train's flat bed car? How many cars are there? Continue down the path. Off to your right there will be an intersection. What is the name of the street that runs alongside the park?
The puzzle starts with the Tree City sign - take the first digit of the number and multiply it by the number of tires you saw on the train and then multiply it by the number of green benches you saw at the playground. Add to this the total number of words on the red "no" sign, and then subtract the numeric value of the month on the plaque. Subtract the total number of vents on the truck engine, and divide by the number of cars. Add the value of all of the letters in the street name (ie. A=1, B=2, etc.). Finally we have the number! Add this number to the North coordinates and subtract it from the West coordinates. The coordinates that you need to use are N42 27.996 W083 11.423
