The physical cache container IS at the listed coordinates! This is a challenge cache and has special logging requirements.
Please be sure to read the cache page thoroughly. Logs of finders not meeting the requirements will be deleted.
You must have obtained at least 1 cache find on every day of the month of January and sign the physical log in order to meet this challenge.
The difficulty is based on the challenge and the muggle factor in the parking lot. But the terrain rating is based on the physical cache location. Bring a pen, watch for muggles, and please replace as found. A good way to do this one would be to park next to the cache (not a light pole), retrieve the container, and sign the log in your car before replacing it.
Cachers may sign the cache's physical log at any time, however, the cache may be logged as found online only after the log is signed and the challenge has been met and documented. If you have your profile set to public, then you don't need to do anything else. If you have your profile set to private, then you will need to prove that you meet the challenge.
P.S. The finds need not have been found on sequential days (i.e. they could have been found in different years).
