The 2009 Rev3 Geocaching Challenge features a series of 60 individualized
Travel Bugs, trackable tags that will make their way to new geocaches across
the United States. Ambitious cachers will benefit from free Rev3 swag just for
entering the Rev3 geocaching contest at www.drinkrev3.com/contests. All
participants will also be entered into a grand prize drawing for a $3,000

"We are very excited about this contest and look forward to seeing all of our
Rev3 Travel Bugs trek from coast to coast, spreading the Rev3 message," said

well as have the opportunity to try Rev3 for themselves, which is why we're

Geocaching is a fast-growing hobby with enthusiasts around the globe. It
combines technology with nature to produce an exciting new form of
entertainment for those who like to be adventurous during their leisure time.
In this modern-day treasure hunt, individuals or groups hide caches all over
the world. The location of each geocache is marked with Global Positioning
System (GPS) coordinates shared via the Internet. Enthusiasts use a handheld
GPS unit to hunt for the caches. The 2009 Rev3 Geocaching Challenge web site
provides curious adventurers with a list of the 60 coordinates for Rev3 Travel
Bug caches as well as general information about the contest.
