I am the co-owner of the Pennsylvania DeLorme Challenge, along with the four other volunteer cache reviewers active in the Keystone State. We chose the most remote location possible for the final challenge, making it a big hiking adventure into a wilderness area miles from the nearest paved road. This is disclosed upfront on the cache page, and emphasized in detail in the informational packet sent by email to qualified finders. Most of the logs rave about the epic journey as a capstone to their travels around the state, and the cache has attracted 11 "Favorites" points. You can rest assured that the listing is 100% compliant with the guidelines for challenge caches.
But, one recent finder was a challenge hound who visited from out of state, dashing from DeLorme Grid to DeLorme grid to nab a park and grab cache in each required spot. Their log on the final cache:
The two of us have completed over 20 state challenges and were pretty disappointed in this one ... agenda, ALR, and basic arithmetic errors. We've done well over 100 4+ terrain caches and we knew pretty much what we were getting in to on all of them. At least let folks know up front they have a 12-15 mile hike through a wilderness.
Yep, you can't please everyone.
