There are a few in the region actually. Yes they are fun if you know what you're doing. Downright dangerous if you don't. The only real drawback is that there are alot of people out there that don't know how to use them properly. It's a real pain in the ass for the rest of us that have put up with the amatuers and idiots that go through them. Supposed to be a bunch coming along Franklin Blvd. Some are concerned about the proximately to the Catholic School along the way. I guess I'm old-fashioned and think too many are not good. Unfortunately elected officials think this is just great, and I can only assume they have visions of glory for initiating these things all over the place. I always call them roundabouts.
