I'm with everyone else, Water is the biggest concern. My main well pump blew a line and flooded my back yard a few days ago. Its out of commission till spring or I can get the money together to fix it. I just thank the good lord we had a submersible elect. Pump put in my other well last spring and unhooked the windmill. I'd be waiting for wind or hand pumping otherwise.
I also hate dealing with hay. They are on grass pasture all summer.
