Judeo-Cache: The Game
A new springtime activity
Spring is officially here. As we slowly emerge from our long winter, many of our activities move from the comfort of our warm homes to the fresh outdoors. My family loves to play games together. In the winter, we sit around the living room playing board games. Now that the warm weather is here, it's time for
In a nutshell, Geocache is a high tech treasure hunt. Participants follow clues and geographical coordinates (latitude and longitude) using a Global Positioning System (GPS) to find their way to a hidden cache or treasure. The fun of geocaching is not only in retrieving the treasure but also in getting there. The hunt might involve solving a mystery or climbing a mountain to get to the treasure.
People have been geocaching since May
3, 2000. On May 1, 2000, the Clinton Administration removed the
intentional GPS signal degradation called "Select Availability
(SA)" opening up high quality inexpensive GPS signals to
civilian applications including this game. Two days later, the first
cache was hidden near Portland, Oregon. The cache was discovered
three days after that. Since then, the game has kept growing and
growing. The official website
lists about 200,000 active caches placed in 217 countries.
A few simple rules govern geocaching:
- You can take something from the
cache to keep as a little souvenir as long as you replace it with another
- Be sure to share your thoughts on the log book that accompanies the cache. (People
who discover the cache will be listed on this webpage!)
- Geocachers are respectful of the
environment in which they play. According to the principles of Tikun Olam, we suggest you bring a trash bag with you on your
hunt, and use the opportunity to pick up littering that you may find.
There are many variants to geocaching --- from
the offset cache (coordinate take you to a location where something is hidden) to multi-cache
(one cache site gives you clues to the next cache site, much like a treasure hunt) to virtual cache
(in which the cache is not a physical treasure but rather an important building or monument).
Our cache has a Jewish theme. The
clues will lead you to Jewish locations in the Main Line near Philadelphia. The distances can be covered easily by bike or by car.
You will need a hand-held GPS receiver. They can be purchased for about $100 at many electronics stores or contact me firstname.lastname@example.org
and borrow hers for the day. (Donations to the Philadelphia Jewish Voice greatly appreciated.)
This is a two-parts cache.
Find the Jewish buildings at the three GPS coordinates below and copy the year of construction,
dedication or renovation inscribed on the building or sign. (All
latitude and longitude coordinates are given here in degrees,
minutes and thousandths of a minute.)
- Latitude North 40º 00.068'
Longitude West 75º 14.338' .
Year of construction: 5 _ _ _ = 5ABC
- Latitude North 40º 00.039'
Longitude West 75º 14.406'
Year of construction: 5 _ _ _ = 5DEF, 19 _ _ = 19GH
- Latitude North 40º
Longitude West 75º 14.406' .
Year of construction: 19 _ _ = 19KL
All these buildings are close to each other, so you can either walk or bike from one to the next one.
Please be respectful to the people
using these Jewish buildings and do not take notes, or use your GPS
or other electronic devices on their property during the Sabbath or
Part I will give you ten numbers
that you will need to feed into the magic formula below. Call the 9
numbers A, B, C, D, E, F, G, H, K, L. Just replace the letters
below by the corresponding digit from the clues above and you will get the location of the cache:.
- Judeocache latitude: North
- Judeocache longitude: West
The Judeocache is hidden some 2 miles away from the locations
in step 1. The cache should be fairly easy to find.
Additional clues can be found on the
page of the Geocaching website.
When you find the cache, leave a note with your comments. Feel free to take an object from the cache.
Our cache has a Jewish theme, so if possible please replace it with another
object related to that theme. Happy Caching.
