My late wife Colette used to say "rising tide floats all boats" in the real estate business. But here, I'm using it quite literally. This is an easy nano. However, it may not be retrievable at certain times of day - especially for the vertically-challenged. "What times of day?" I hear you cry. Well, you're going to have to figure that out on your own. Do not go for the cache if it is out of reach. There are many eyes watching so please don't draw attention to yourself or the cache.
The park and dock are public access. However, if you are not a resident or guest of a resident, you can't drive onto the island. You'll have to park off the island (e.g. the Vons parking lot) and walk over the one of the bridges to the cache.
