one thing I have successfully done is to get in the eyesight of a hard to catch horse and crouch down. A lot of horses will walk up to you out of curiousity and you can commence with the scratching or whatever it takes to show them humans are okay.

Yep.  When Gia runs away when I hitch up the trailer I just go stand in the pasture by the gate while she peeks at me from behind a tree.  Then I turn my back on her and count to about 20.  If she isn't a foot away from me when I  turn around, it's a rare day.  And she doesn't bolt away once I go to halter her.
