Carport using unusual construction method

Why did you choose the concrete pillars over 6x6 lumber?
Mainly because it was a different way to do it, and since I am doing it myself and it is going to be labor-intensive in any case, I thought it would be more interesting to build, and maybe have more visual appeal this way. So far I think I am right. It has been a lot of fun building it, and I like the way it looks.
