The cache is NOT at the posted coordinates! However it IS the first stage of the multi, so please start there.
This is a five-stage multi cache that keeps you running throughout the Swamp Creek Park and Ride.
1) Go to N 47° 50.993' W 122° 16.541'. Look for the station number. That number is "AxxB".
2) Go to N 47° 51.008' W 122° 16.585'. Count how many routes pass through the station. Let that number be "C".
3) Go to N 47° 51.012' W 122° 16.600'. Look for a large two-digit number. Let that number be "Dx".
4) Go to N 47° 51.086' W 122° 16.590'. Look for an address in the form of "xxxxE" B Hwy 99.
The final coordinates may be calculated from the following equation:
N 47° (E-D)(D).(A)(E-D-D)(B)'
W 122° (C-B)(E).(B-D-D)(B-E)(E-D-D)'
Congrats to rambudo for FTF!!!
