Wow! Lightning zapped your internet! It sounds like you have a real mixture of good and bad things going on. Tell us about the horses. How'd you get started keeping the old racehorses, and are they yours or boarders? Constant wet conditions are bad for horse's feet. Too much opportunity for bacteria to invade. Sorry about your weed invasion. I can relate to the constant battle with weeds. Just get the early ones under some kind of control and the later ones take over.
