We have found many a cache hidden amongst the rocks - some have been very difficult. One in particular, that we found while overwintering in Arizona, took us three attempts and a couple of hours in total to finally get it. When we eventually found it, it was like "and this was here the whole time in plain sight???". Perhaps we have all had that experience?
Bring your own pen. Do NOT climb on the rocks - it is within arm's reach from the sidewalk. No need to turn over any of the rocks, and yes it is sitting in plain sight! Parking available very close by. Watch for muggles!
When replacing, it's good to nestle is up against other rocks to blend in, but please do not cover it with other rocks.
