When The Callan Crew patriarch attended university, he majored in math, having lettered in tennis in high school. Now, years later, with a family that includes twins, he thought that it would be fun to create a mini-multi cache to bring together his love of number theory, tennis and the strong family bond that twins share into a challenging and fun cache for his geocaching friends.
This cache is located in the R.S. "Dad" Dunham Park, which you will find to have very nice tennis facilities as well as a sandbox and a couple of well equipped playgrounds and basketball courts. We hope that you take advantage of this charming park while you hunt for the caches. Have your young kids walk the brick maze while you get your bearings or do the math between stages. This is a small city park, so this is a kid friendly cache that will not require much walking.
The final stage of this multi-cache features a small container within which you can exchange geocaching buttons, travel bugs with small hitchhikers, geocoins and other small items. In addition to the smiley-face log book we have initially stashed this cache with several geocaching buttons (including a First To Find button for the first finder), a metal desktop sculture, a heart shaped mini paddle-ball kids toy, a compass carabiner, a ladybug tatoo, the Take Me Away travel bug and our very own Cyan Glo Fish travel bug, which we are launching in this cache.
Cache Notes: The first stage container must be removed from its hide and opened to reveal the clues. Please replace the cache in its exact hiding place so that others will not spend all day finding it. The final stage container must merely be opened to reveal its cache of goodies. Do not attempt to remove this container. Simply open it.
Coordinate Notes: Both stages of this multi-cache have been positioned for over five months so that we could observe and average coordinates and make sure that the caches would remain without muggle intervention. The coordinates are precise and match the math exactly. Do not make any mistakes in your math, or this will become an extremely difficult, if not impossible, cache.
Please keep all spoilers and hints out of your posts. Disclosing posts will be deleted. We want to keep this one a bit challenging.
NOTE: You will need this entire cache description in order to find the cache.
Determine the last three digits of the Latitude of stage one by beginning with the last three digits of the Longitude of where you parked the car. Subtract one from the digits summed and multiply the result by the portion of a minute that these three digits represented in the Longitude divided by ten. Next, add back the one that you subtracted before to yield a number from which you should subtract the sum of each of the last three digits of the Longitude cubed.
Now add the first digit of the Longitude of where you parked to the last three digits of the Longitude of where you parked doubled. Subtract this result from the last three digits of the Latitude of where you parked to yield the last three digits of the Longitude for stage one.
Keeping all coordinates the same, save the last three digits of both the Longitude and Latitude determined above and go find the first stage.
At this stage you will find a very small container that will include several values to help you determine the coordinates of the second stage located within the same park. When you have these values, plug them into the directions that follow.
Multiply by A the sum of the last B digits of the stage one LCitude to yield a result that when added to the last B digits of the stage one LCitude will in fact determine the last D digits of the LCitude of the second stage.
Finally, subtract the Xth digit of the LYitude raised to the Zth power from the last D digits of the LYitude of the first stage to yield the last B digits of the LYitude of the second stage.
Have fun and thanks for seeking our caches. We love hearing from you.
The Callan Crew
