While on pony, you can open any gate. She's a pro at it. Except, you have to want it.
She's so little (around 14 hands) that there's no bending over and down involved! However, when she starts to lose it, you have to stay right with her and let her know you mean it.
And here is the result of opening that dang gate.
But man oh man, did we work on it until we opened and closed the gate behind us.
