And if she asks you why you can tell her that I told you
That she's tired of Caches in the Air
I've got a find I want the world to share in; Caches on walls
Just leave me to despair

When they are meant to be winter friendly hides, they end up being Caches in the Air (with apologies to Don MacLean; click on the pic if you would like to hear the title-inspired song).
Given that the Bayman here is fairly vertically challenged, it is hoped that this winter friendly cache, placed in the spring, is not too high in the air.
