turuthok: It's a tough decision, but it's time to archive this puzzle cache. Before anything, I'd like to say a big thanks to the property owners who let me even placed this cache there. I know it's a sacrifice they made ...
I had wish to move this cache somewhere else, but unfortunately, there's no nearby location which satisfies the theme.
So, this is it!
Solvers can still try as I have a certitude for it. And once again, there's a billrow puzzle mentioned in the cache page which I believe is still active and is using very similar technique ...
Thanks!!
