The past two days I've been digging rock. It takes a lot of time to fill a wheelbarrow full of rock. Yes, I could have some delivered from somebody who sells this stuff, but the Nearing's gathered their own---so by golly, so am I!
I've gotten most of the rock for the trenches from the pile created by the excavation. This pile needs to be sifted anyway, so I dig and dig. I pull out suitable rocks ("up to as big as your head" Joni says). There are times in my life when my head has been quite big (usually followed by some humbling experience)...so most rocks are fair game.
