Many people like to do Challenge Caches. The requirements are different for each challenge, but one that we enjoyed doing was a Rainbow Cache. However, we found that indigo was a very hard color to find although we found a cache with that color in South Carolina. We thought we would try and help people out by placing a cache with that color in the name closer to the actual challenge.
You are looking for a nano placed in a usual spot. Parking is very close.
If you like to do challenge caches and need a word or number to complete the challenge, please message or email us and we'll be happy to include that word or number in the title of the next cache. We are planning on putting out many challenge helper caches if fellow cachers get in touch with us. Please let us know where in the title the word or number needs to be such as the first word or anywhere in the cache.
