Please be extremely careful, parking completely off the road. Watch your step, be careful of glass, loose stones, water when present, animals, thorns, getting poked by low-hanging branches, etc. Please replace carefully and precisely as found to protect for the "long term".
Some of what I have told you may be "hints", but most of it should be taken at face value for your safety, which for MOST people is far more important than getting the "smiley".
This is NOT a park and grab, and is NOT recommended for night caching.
