I have my garden surrounded by a fence composed of 52" cattle panels loosely held up with t-posts. To each t-post I wired a two foot piece of pvc. Then I strung two runs of nylon cord to the pvc, with the top run at about seven feet for the most part. I got some cheap plastic marking tape and tied pieces of that to the nylon cords. Even though in this drought the only even damp spot on my property is my garden, no deer have gotten in. I've used this for two years now and have had no problems. I take down my fence in the fall and re-erect it in the spring so I can use my tractor and tiller to work the spot, so I need it to be quick and easy to set up and take down. Works for me. YMMV.
