I currently have 61 souvenirs as can be seen from my profile. I'll attach a screenshot too.
We moved on to this one from the Elementary Challenge, and saw a squirrel just as we arrived at this one too. I spotted something that matched the hint, had a look and there was the cache neatly tucked away in its hole.
A nice easy one. This was another one for me - and that means I lead my son Bobcat 3:0 on finds at the moment.
