Patio timetable! Hopefully, anyway...

Today or tomorrow Call aggregates place to order crushed rock, sand, topsoil, and possibly mulch while I'm at it; get marking paint, mason's line, line level, and stakes from Home Despot
May 18 Go get rocks with help of UHaul van and brute squad
Sometime next week Mark outlines of patio and paths; possibly start digging, depending on weather
May 22 Have aggregate stuff delivered
May 23 Dig out, fill, and compact foundation; install heavier rocks
May 24 Install rest of rocks, fill cracks with topsoil, and plant creeping thyme/moss
