@djjd62,
I put a sign out in the front of the lane that says "WATER FOR HORSES". Its been real hot and the amish have their buggies being pulled by these sweaty horses. Yesterday, there was an AMishman who had the hose turned on (We have an old irrigation well all hooked up out near the edge of a field) and he was washing his horses hooves.
Apparently the heat on theior hoofs can cause them to founder if it gets too hot on em. Remember a hoorse is walking around as if we would be if we were walking on our middle finger.
