The Limestone Quarry

Directly over the hill from in front of where we live is a limestone quarry.  Everyday at sometime between 3 and 4PM usually they blast for stone.  It shakes the house like an earthquake and then a puff of dust comes from over the hill. Jake drove us over there by way of the pasture to see the quarry on the backside of the hole. The quarry is operated by a family. 

I get so frustrated with limestone vocabulary, 57s, screenings, 4s, 2s, 304s.  If they sold this stuff at Walmart they would have to rename them to something more logical. Don't you think?
