The challenge cache IS at the posted coordinates. Challenge caches are a great way to celebrate milestones. Please read below for the logging requirements for this challenge.
To fulfill this challenge, you need to have found at least 25 wherigos. It took me quite a while to try out wherigo caches. Now, I think they're great! Currently, Oregon has 57 wherigos to choose from.
You are welcome to find and sign the log at any time. To log “Found it,” you must also qualify by completing the requirements. If you don’t yet qualify, simply “Write a note” and log the cache once you do qualify. Please use the checker below for verification.
The hide itself is fairly simple, a park and grab, although in the winter, waterproof footwear may be needed. The D/T rating reflects the work in finding the caches to qualify for the challenge. Please leave the container attached. You might need a tool to extract the log.

Congratulations Geo-Jessi on FTF!
