I've always disliked those posts.
This teenaged boy was over at our house the other day. Thoughtlessly, he grabbed onto one of the posts like a monkey and accidentally dislodged it. Holding a piece of our house in his hand, he and his mother were both horrified! I was delighted. I never knew that removing them could be so easy! It took less than half an hour to remove all of them (there was another wall of them, too, facing the back door. The kitchen was imprisoned!) When or if it ever warms up, I'll sand it down and revarnish it.
