Geocache Description:


The cache is NOT at the posted coordinates. To find the cache, you must solve the following puzzle.

I really wasn't planning on putting out any more puzzle caches, but I found this little ditty too cool to resist.

YOU WILL NEED A CREDIT CARD TO SOLVE THIS PUZZLE CACHE!!

This should work with any credit card in your wallet. Take the SECOND set of FOUR digits from your credit card and arrange them in ascending and then descending order to get two 4-digit numbers. (Add leading zeroes if needed). Subtract the smaller number from the larger one. Take the result and again arrange the digits in ascending and descending order and repeat. Stop when the answer is the same as it was in the previous step. (You should not have to do this more than 7 times).

Take the resulting 4-digit number and sum the digits. Multiply this sum by 5 and add it to this North coordinate 46 29. 154.

Now, take the LAST THREE digits in the final set of four numbers on your card and do the same. Arrange in ascending and descending order and subtract the smaller number from the larger. Repeat again until you get the same answer again.

Take the resulting 3-digit number and subtract it (as is) from this West coordinate 63 59.648.
