The walls/posts on the outdoor run that I'm building now will be eight feet tall (ten feet with two feet in ground). My world will go around a lot faster if I use two rows of 4-foot high 1/2-inch hardware cloth because I cannot find 4-foot high 1/4-inch, only 3 foot. What are the benefits of having 1/4 inch along the bottom of the run; can a coon reach through 1/2 inch? If so, I'll use 1/4 inch and plan to do something else with the top one foot of the posts.
