Once you see the bridge and its surroundings you will understand the rating. You will find a well camoed cache. It's best to find in daylight. Please no hints in your logs, even subtle ones like I'm glad I'm tall. If you can't find please log a DNF so I can adjust rating. Good luck and $5.00 for FTF. If you get frustrated easily just DNF now and skip this cache.
