Tickle is defined as a narrow salt-water strait, as in an entrance to a harbour or between islands or other land masses, often difficult or treacherous to navigate because of narrowness, tides, etc. This cache is located near the tickle bridge and although water shouldn't come into play, care should be taken from the rocks and from muggles in vehicles, muggles walking, muggles nearby ...well you get the picture. BYOP. Remember - the decision to search for any geocache and the responsibility for your own safety lies with you.
