Found this sign laying in the grass under a juniper tree right where @Grasshopper and I had left it on a hike back in 2016. It has weathered a little and some cow had no respect for it. The meaning of the words engraved in this thick plank was a mystery back then and still is. But some recent searching on Google has led me to think that it is referring to an on-line video game, Trove, and a "fan-run community website" for that game called Trovesaurus. I'm waiting for an expert's opinion. He's my grandson who has been an avid on-line gamer for years and will be getting his masters degree in computer science in May.
