anyone build an arbor?
I want to build an arbor and am thinking about using conduit pipe and hog fencing. I am in a windy area, so the posts would need to be in concrete (I think). I would also need to have verticle posts closely spaced (I think)and lots of cross members (I think). The arbor needs to built in 3 sections, the two outside sections can be normal heighth to walk under, but the center section needs to be about 14 feet tall and wide enough that a bus can turn in that area without hitting it. I want to grow wisteria or grape on it, but an annual be okay too if weight is a problem. I have read about using pvc pipe for this, but I live where the sun is the most intense for about a third of the year and I worry that it would break down the pvc. What do you people think? The arbor would need to be a total of about 75 feet long, though it can be in broken sections with "landings" in between.
