I was born at 5:55 PM on the 5th day of the week (Yes, really) so I am creating this series of geocaches to the number 5. This geocache will require you to have already found five D5/T5 caches plus five D4.5 caches. The 555 is for the 5 5/5 requirement for this cache. The Four and a Half is for the 4.5 in the Difficulty requirement for this cache.
If you have not yet completed this challenge, you may still find the geocache and sign the log, but you may not log it as a find until you have successfully completed the challenge. Any found-it logs submitted without completing the challenge will be deleted.
The rating for this cache reflects the effort required to complete the challenge; the hide itself would be rated a 2.5 difficulty and 4.0 terrain for this challenge cache.
