The only bad thing about bribary in my opinion is that when I give treats every horse will begin to nip me when I catch them because they want the food. Otherwise its great, if you don't mind the biting!
Go sunbathe in the pasture. Tie halters to your chair and in trees, along with yourself. Show her that everytime you go in there you aren't going to catch her. Besides, the weather is getting nicer. Surely you could use a tan? I know I'm pale as milk since winter, which means the time has come to give my horses a valuable lesson
