Thanks, Bob! It IS important to know these things, however, my horses are nowhere NEAR my tomato garden areas. I rotate them between my big garden, bed around the cistern (south of the house), bed south of the garage, and the old cattle fencing by the street. Unless my horses escape, they go nowhere near my tomatoes. I WILL say, people SHOULD listen to the advice of old horse people. There was a story of some girl's horse that broke it's neck bc she looped a stallion lean To the halter, horse got his foot caught in the chain lead and broke his neck panicking. I commented that it was stupid to do this, bc a stallion lead is a horse lead with 20 some inches of chain link used to put through the halter to control a stallion. I was called insensitive.
You NEVER loop it through the ring on a horse's halter. Usually, it is removable, and when you don't need it, you remove it.
We horse people ALWAYS, ALWAYS have to be one step ahead of our horses, so that they don't hurt themselves. My excellent 22yo stone broke mare has a stall where I have put in a support to help with the weight of yearly hay, 400 bales/~65 lbs each. It sits about 18 inches from the corner of the stall opening. I have looped 1 1/2 inches of a strip from a lightweight ratchet 3 ft high to prevent her from Trying to exit through the small space, where she would get trapped and then panic. It has been very helpful and Necessary.
So...thx, Bob!
