Exactly, luck is what I need. She can not be distracted when we are at the park. Balls and frisbees mean nothing to her. She is a follower and loves to chase any dog that runs. She has also been running over some of the smaller dogs. But my outlook on that is don't bring your small dog into the big dog park if you're worried about them getting ran over. And I've never had an owner get upset for getting "rolled" by Zoee......yet.
I'm not against muzzles, but honestly I don't think I could bring myself to put one on Zoee. She can't even handle a gentle leader over her nose. I'm sure if I had a muzzle on her she would freak out. If we ever "dress" her up with glasses or hats and things she freezes and won't move. And I don't think we are at the point to need a muzzle. I sure hope we NEVER get to that point either.
I guess I could tuck her leash into her collar so she'd be easier to grab. With her long hair it's hard to find her collar quickly.
I'll try the park again in a while. I'm not giving up on it. I am just afraid of her hurting someone elses dog. That would kill me.
I seriously think it was the incident with the Husky. I believe she is afraid that another dog is going to do what the husky did so she is reacting before they have a chance to. Does that make sense? How would I break her of that? Maybe I'll try her on leash and see how she acts for a bit.

Thank you all for your advice and suggestions. I do appreciate them. And I'll keep you updated on our next visit to the park.
