The header coordinates are for the park entrance on route 117. You will be applying a simple equation to the following coordinates: N41 07.171, W73 47.890. Be careful with the decimal points!
Take the North coordinate, 41 07.171, first remove the space, 4107.171, remember to add the space back in to the final number. Divide it by 5, subtract 1.27829, add 39.2, divide by .07, multiply by 2, add 124, multiply by.5, subtract 17, divide by 3. Your answer (with the space) is the North coordinate.
Once you have the North coordinate, you will know how to get the West coordinate.
