We have two "patience poles". They are poles purchased from the electric company and cut down. They are about 4' in the ground and about 10' above ground. Then old tires are dropped over them all the way up. Bob ties the horses to one of the tires, which will turn so they don't get wrapped around the pole but they can fight it all day and get nowhere. Any horses that we have that are bad about standing tied do time on the patience pole.
I'm very regular about making my horses stand tied. Even horses that are very good, it's a good thing to do with them. Harley almost always stands saddled for anywhere from 15 minutes to an hour before I ride. And lots of times he stands there for awhile after I get back.
It's such a simple thing to do but the benefits are huge, IMO:)
