Stage 1 is a virtual spot. Solve for Stage 2 using Coords N 45 A.BC and W 092 Y.Z.
Stage 2 is a physical spot. Look for a container.
Stage 3 is a virtual spot. Solve for Stage 4 using Coords N 45 A.BC and W 092 Y.Z.
Stage 4 is a physical spot. Look for a container.
Stage 5 is the final.

At Stage 1(Starting Coordinates):
A=Notice the security panels made from galvanized wire in a grid pattern. Each grid has how many horizontal wires subtract 13.
B=Looking East you will see a street sign. Count the number of letters in the street name(the whole name).
C=How many bolts support each vertical square pole on the bridge add 3.
Y=How many vertical posts on the West side of the bridge from one side to the other subtract 28
Z=Find the Specification Plate for the bridge at the NW corner of the bridge. How many tons can this bridge support multiply by 18

You can validate your puzzle solution with certitude.

At Stage 3:
A=How many vertical black fence poles are connected to the bridge deck on the West side subtract 3
B=How many bolts are in a cluster fastening the thick boards to the side of the bridge subtract 3
C=Count the number of 2X6 boards that lead up to the bridge on each side and on each side(yes, I said that twice)and (only the ones 'facing out') add 61
Y=How many 2.5X10 boards(the thickest ones) line the bridge and subtract 1
Z=Use the starting values for A+B+C+Y. Subtract 072(keep the zero where it is in your answer)
