I have 63 of the squares filled on my D/T grid. My stats are viewable but I'll attach a screenshot of it anyway.
We'd been dawdling along the path as a dog walker was behind us. In fact we timed it very well as she caught us up and passed us just as we arrived at a likely-looking silver birch and laurel bush combo.
Bobcat went in followed by me, but neither of us could see anything there. So after a minute I went out to see if we'd stopped too early. Bobcat was just about to give up and join me too when suddenly he spotted the cache. Nice one - that makes the score 4:2.
