(this is just a joke - of course farmwork still has physically demanding parts)
It's amazing what you can DIY if you're willing to put in the time and muscle! Oasis made me think of my wife's cousin''s backyard outside of Sacramento. He put in a few small shade trees, lots of overhead trellises with vines and stuff on them, and burbling water channels here and there. On hot summer days I swear it's 10 degrees cooler back there.
