Back in October I wrote about my "island garden" — meaning the plants I'm growing in a raised bed in the center of the road in front of my house. It's part of a chain of islands going down my street and the center of many of the streets in my town. They're actually "traffic calming islands" intended to slow down drivers by forcing them to brake to get around this jog in the road.
There's a metal post with a traffic sign in the middle of the bed in case drivers are confused. They don't seem confused on my street, except about the speed. I've had a city crew come out a couple of times to replace the post, the sign and the big hunk of concrete that keeps it upright, after someone has driven into it.
