As per challenges, the logsheet, at the posted coordinates, can be signed at any time but the cache may not be claimed until the following conditions are met:
1. Identify ten different caches, each one starting with the letters G-O-O-S-E-V-I-L-L-E.
2. Each cache must be of a different icon / cache type.
As per custom, I do qualify for my own challenge.
