The cache is not at the posted coordinates.
Welcome to another cache in this series. A lot has changed since the last cache in this series, the names of the caches are all different, this is the first Multi-Cache in the series. (I realized that the caches in this series should be classified as multi caches a little while ago, which is why I changed the name for all the caches.) Anyways to find the final coordiates is simple. From the posted coordinates ride the Q or F train one stop to the Coney Island-Stillwell Avenue train station.
If you rode the Q train when you get off walk up to the big balcony that has access to all the train platforms. Then turn around and look on the sign that is right above the stairway from the balcony to the train platform. On the sign you will see two numbers that are next to arrows and the words track. The arrows point to the two different tracks the Q trains arrive on. Remember the two track number and go to the next place to gather information. (If you took the F train to the Coney Island Station just walk on to the balcony and over to the Q track where you can find the information.)
Then you will walk oover to the F platform an collect the same information. Above the stairway between the platform and the balcony you will see the same sign as the last sign, just this time instead of having the Q symbol it has the F symbol, and the track numbers will be different. Remember the two track numbers and go to the last place for information.
You will actually walk back to the Q train platform again. Count how mant stairs there are between the Q platform and the balcony. (Just in case you count one extra stair or subtract a couple by accident the answers will all be pretty far in numbers away from each other so you can just round to the nearest answer if the answer you got doesn't matchany of the options. Some people count stairs different than others, and that's fine.)
