Kabby,
Seeing your post reminded me of one other thing that worked for me years back. I did something similar, but with Christmas tinsel garland strung between the posts. I had posts about 6 feet high, and 3 or 4 levels of the garland around the perimeter between the posts. The shimmery garland seemed to confuse the deer, and they stayed away from it. That was a temporary solution I had years ago at a house we were renting for only a year or two.
