We were out doing maintenance on our caches here (in 97 degree weather!) and figured this spot could use another. BYOP.
Please note - you must arrive "by sea" to stay legal here, do not cut through any yards, that is trespassing. The terrain rating reflects the need to travel on water. A public water access waypoint is listed. As with any water based cache, this is in a potentially dangerous location and seeking it is done at your own risk!
