I was caching with my daughter Enchanted Fox today. We were mainly picking up puzzles - but I noticed a few challenges like this one that I had qualified for so we included those on our list too.
We found a nice parking space around the corner. We were a bit worried about the warning sign but the good hint meant that we didn't have any problem finding the cache. Just as we were walking off I spotted a fox in the wood. He froze when he saw us but then when we didn't move he seemed quite accepting of our presence and just sat down. So we took a couple of photos before he moved off.
My D/T grid isn't complete but I do qualify for this challenge as can be seen from my profile. However as the cache page says a screenshot of the challenge checker is preferred I will attach that.
