The cache is not at the posted coordinates. Solve the puzzle to determine the cache location.
This cache is inspired by a cache by mswma that I found in Massachusetts. I found there were also signs of Superman (well... not Superman, but the same friend as in Massachusetts!) here in Fullerton, so I decided to make my own puzzle. Once you find the signs (they are within 1 mile of the posted coordinates), you'll want to make note of the coordinates of each location. You do not need to physically visit either location. The coordinates are N 33° ??.??A W 117° ??.??A and N 33° ??.??A W 117° ??.??A where A = number of letters before the hyphen in Superman's birth name.
Superman can take a direct flight of 2393 feet at 5.2 degrees from one of these signs, and a single bound of 1480 feet at 354.7 degrees from the other to reach the cache. You'll need to do some solving to determine the final location. Parking coordinates will be provided in the checker; street sweeping is posted 7am-noon Fridays.
You can validate your puzzle solution with certitude.
