Your transformation to find this cache will have several components:
Cabinet 16 & 15 & 14
Look high, look low, look all around at each of these specific works of art, to glean the information to solve the two equations.
Equation # 1: A radius from one of the transformers
Equation # 2: A bearing from one of the transformers
Where these two lines intersect you will find the cache.
Radius:
The radius from the ___bulbs lamp post is: "Warning" ___517
Radius: ___ ___ ___ m.
Radius: R1 R2 R3 m.
#16 R1 = SP43___03
#15 R2 = SP___3862
#14 R3 = 221-671___
Bearing:
The bearing from the fat tires is: ___ _5__ ___.___ _5__°T :: A 5 B . C 5 °T
#16 A = ___24-670
#15 B = 30___KVA
#14 C = SP4___81___ = ___ + ___=___ !!!
The final solution will only get you close, so maybe a ~ Déjà vu ~ experience will be very helpful and use his datum Ø492622 mE & 4488762mN when he made is famous flight.
