Late starter here, playing catch-up.
Not the point of the markers, but I saw right away. Reflections.
I'm not saying any more on that here out of respect.
Now to focus on the markers themselves.
This is more challenging than 3301 for me.
I was referring to the Cicada 3301 challenge. The watch markers Q threw out there for us is what I'm looking at right now. This appears harder than that to me. Aside from that, (side challenge?) "If you look close enough you might see…." well, I did, and I did.
