Cache is on the coordinates. You must meet certain requirements in order to log in the find in this cache.
To complete this challenge, you must have found at least one cache in a day for 31 days in a row.
Before logging cache as "Found" on the internet, of course you have to visit the cache and sign the logbook.
But you can not log the find until you meet the requirements (in this way you don't have to return to sign a logbook after meeting the requirements!)
To prove you have fulfilled the requirement, paste your result from the checker.
