I love a horse that ground ties. I taught my cremello AQHA mare to ground tie (it is easy to do, you just enforce the "you don't get to move a hoof unless I say so rule" when you are around them) and it was so convenient!
I could take her out anywhere, drop the lead rope and VIOLA! my horse would stand still. I could bathe her on the driveway without anything to tie her to. I could leave her on the driveway and hurry into the barn for something I forgot and (within reason timewise) she would wait for me.
The experts say that a horse that won't tie hasn't been trained properly to release to pressure when tied. John Lyons has an AWESOME and easy to follow method for teaching horses to tie.
The basic concept is to tie problem horses in such a way that the rope gives slowly to the pressure. They have those tie ring things that you slip a rope through that can do that, or you get the same effect by winding the leadrope around (many times) a sturdy but slick metal tie bar.
When I first got my Crabbet Arabian gelding at age 13 he wouldn't tie without fighting against the rope. We used an intertube tire (aka *very* sturdy stretchy rubber) and tied him to that.
The tube would give when he would fight against it and it was tiresome for him to stretch the tube so eventually he decided it was easier to just stand tied. After he stopped fighting the tube he was 100% cured and he never fought the rope again.
My AQHA mare would occasionally flip out and fight the lead rope, usually once every 50 times she was tied, and I got her at four months and did all her training myself so I am not quite sure why she would flip out. I always assumed that horses had some traumatic experience that caused them to fight the lead rope, but she defies that logic.
One of the keys to keeping a horse sane when tied is avoiding any situation where they will panic and fight to get away from where they are. So I never tie when introducing new things, and I make sure the horse never gets rewarded for fighting with their freedom if a halter, rope, or object tied to breaks.
I also have learned never tie a horse to anything that can hold up to a horse's full weight. Period. Even the most docile horse can be stung by a bee and flip out, and if they break the rope/halter/object tied to they just got rewarded for fighting the rope with their freedom.
