Last year was my first year in the new house, so I built a fence for it. I used 1x3s for the boards and made it in 4 foot sections. 1/2" PVC for the spindles, and 3" PVC cut into 1" sections for aesthetics. Use 3/8" rebar 24" long. Pound into the ground, 2 rebar for each 4 foot fence section. Slide the PVC over the rebar and boom. You've got a fence that won't fall over, and can withstand some serious winds. Also with this method, you don't see what's holding it up. Took some time and some power tools, but it's well worth the effort and people love it. Here is an under construction photo.
