This is an urban 5/5 cache that requires special equipment. You'll figure that part out. Again, please DO NOT attempt this without someone along, and DO NOT attempt this if the creek is in flood conditions. Also, parking in the nearby apartment complex parking lot is NOT permitted, and may result in your vehicle being towwed. Please be careful with the cache, do not remove from it's "location", and report any issues so that they can be addressed promptly. There is some swag in the container to start.
This cache was placed in a pouring rain. It made for a great adventure. However, I wouldn't want to FIND it under those conditions! Nor would it be a good idea to attempt this at night.
UPDATE: It was REplaced to a new location due to proximity issues, and made us even more certain of the risk of attempting this alone; I slipped on the bank of what I though was a small drainage area, 5 feet wide, and ended up in 3' of really nasty muck! On the plus side, AMT saw a red fox. Maybe your adventure will yield similar memorable stories!
