I saw that there is no cache nearby that has this rating so I wanted to put one out that would help all you grid hunters. The cache itself can be tricky to see (hence the difficulty rating). The area where this cache is tends to flood with the tides and when there is heavy rain (hence the terrain rating). For some of you, this will probably be much easier that advertised depending on the time of year you visit the cache. During the summer and at high tide, this cache will make you earn your grid square. There is plenty of parking roadside, so please pull over safely.
Thanks to PhMJ for helping to find the location for this cache.
