Placed as a navigation marker to aid folk in negotiating this track. As it turns out, cache is a few meters off the track, but will be very easy to find. I hope.
Bring a pen. No room for trackables or swag. Or rubbish - please take your rubbish home.
If the day is hot, wear sunblock. If it is raining, wear a raincoat. Or get wet.
Could be considered a Park'n'Grab. If you are coming by bicycle [:)]
