Tigey Wigey & Piglet: I have been out to the location and checked the entire length of the boardwalk for suitable hiding places. None I deemed suitable for a long term cache. Given this one started life out as a "reach it from the boardwalk" and following the demise of the convenient hollow log was moved to a place that involved departing the boardwalk, which some see as not good practice. Given the amount of people frequenting the area and the rise and fall of the tide made this a difficult location to hide the cache in the place I wished, to show off the boardwalk, rather than just the area, I have very sadly decided to archive this. Thanks to all those who found this over the tears.
