What are lab caches?
A Lab Cache is an experimental and extremely rare geocache type. These geocaches are a way for us to innovate and test new ideas to make geocaching even better. What is a Geocaching Adventure geocache? This type of Lab Cache was developed to offer private or time limited geocaches. These geocaches are a way for Groundspeak to innovate and test new ideas to make geocaching even better.
How do Lab Caches work?
Lab Caches are similar to regular geocaches: navigate to the location and find the cache. However, these differ in that you must use a specific code found at each location in order to mark the geocache as found.
WHERE DO WE FIND LAB CACHES?
Geocoinfest's Lab Cache will be within a 6 mile radius of the Queen Mary. There will be 10 different Lab Caches for you to find. Each one will showcase a different point of interest we hope you will enjoy visiting. At each point of interest, you will write down a special code word or words that you'll use to log the cache.
Our lab caches will be published Friday, October 13, 2017 in the evening. Time is still to be determined.
