I recently picked up a href="http://www.garmin.com/products/etrexVenture/index.html">Garmin
Venture GPS and started playing the href="http://www.geocaching.com">geocaching 'game'.
The idea is you visit href="http://www.geocaching.com">geocaching.com and print out or
download into your GPS the location of a cache. Then using the GPS
navigate to the cache and see whats inside. Typically there is a log
book and some trinkets that you can swap out for whatever trinkets you
brought. Some caches have disposable cameras so you can take your
picture and leave for the maintainer of the stash. The last cache we
found was a multi-cache site in a cemetery. The first
latitude/longitude location was a grave site where you did some simple
math on the person's birthdate and that goes into part of the next
latitude/longitude location and so on until you get to the final
cache.
In the last
week the boys and I have found href="http://www.geocaching.com/seek/cache_details.asp?ID=7183">fhref="http://www.geocaching.com/seek/cache_details.asp?ID=6641">ohref="http://www.geocaching.com/seek/cache_details.asp?ID=158">uhref="http://www.geocaching.com/seek/cache_details.asp?ID=5008">r
geocaches all within 30 miles of home. They can't wait until next
weekend to find some more!
