I hear ya, db.

We all have our systems that "work".  None are foolproof.  I know bears do go to smaller islands, but it's been my experience that they visit those campsites less frequently than mainland campsites (unless there's something yummy on the small island to draw a bear there...)

We just all have to find a spot on the risk-reward curve that makes us comfortable and that is where we camp, system-wise.
