Cool concept, Zep! I love "outside of the box" problem solving.
My old father and old uncle sometimes go out to the farm and it is definitely a chore for them to get out and get through some of the gates that I have stretched tight.
Plus, just think how stylish I will look when I drive my gull wing Ferrari into the farm.
I assume that the foot plates look enough like "pipe cattleguards" that cattle won't walk on the mechanism and let themselves through the gate.
