Dave, having read this link about the owl it would be a great puzzle to solve....eventually. I’ve been reminded by other smart finders to put my remaining energy into real targets and interests. They say the clock is ticking, and say speed I dig is slow and better ‘hurry, to move onto the next’. Even the fastest diggers will be late to some. Find that likely spot. Then dig. Mind those rocks!! They don’t give easy, get round them, under if not, age is a curse. Should have been nicer to these hands when younger. There’s time, so take it easy. Jus’sayin’.
