My Granddad's Ghost Was Hiding on Hilbry Island

As a kid, it scared the life out of me. If he felt my Granddad's presence on Hilbry, then his spirit must have been hanging around. I remember grabbing my mom's hand and quietly asking her, is Granddad Fred really here? She was struggling to hold back tears by that point. We had at least 50 minutes to spare, so there's absolutely no reason why we should have been worried about the tide coming in.
