At the posted coordinates, you'll find a bridge and sign from which you'll need to collect some information.
- A = load limit (in tons)
- B = unicycle (in tons)
- C = bicycle (in tons)
- D = tricycle (in tons)
- E = truck (in tons)
- F = bulldozer (in tons)
- G = number of yellow supports on the railings of the bridge (total incl. both sides)
Then proceed to N 49° 20.[(D×2)+E+G+(C×2)−10]' W 122° 44.[(F×8)+(B×2)+A−1]' to find the cache. Use the hint.
