This is an attribute challenge.
I like a good challenge. Many do. This cache is at the posted cords, but in order to log your find online, you must meet the challenge first! You can note the log with your signature at any time. This cache does NOT qualify for the challenge. Of course past finds count.
You must have found more than 150 geocaches with the <10KM attribute. You can use the checker to see if you qualify!
