Granite Hill Quarry Raymond NH

My fiancé's family owns Granite Hill recycling and quarry off rt 27 in Raymond nh. we go there occasionally to go shooting, I noticed recently there's a bolted line on a small cliff right near the dirt road from the main pit to the back quarries. Wondering who put it there and what grade it is. I figure whoever did it probably comes on here. BTW - its posted no trespassing and im surprised someone even found it let alone bolted a line there. My finance and i climb and want to know what grade it is and if there's more.  

First rule of Climbing-In-Posted-No-Tresspassing-Area-Club is dont talk about it

You invite people to come climb it and get a consensus.

if this is the area just before the power lines on the left? I Climbed there in the early 90s. The line is called Green Eggs and Ham. Possibly hard 11ish.  We were talked to not long after and stopped visiting shortly after. The area looked a lot different Then, cliff was obviously a bit more hidden.
     Not sure I’d trust them…. We were in high school. Ha
