Dad gave the kids this roller-coaster a long time ago. The kids dragged it out Saturday and spent 8 hours putting it together. They got a little frustrated that they couldn't get the car to stay on the track, so we had to call a time out. Jim worked with them a little and they discovered that if they tweaked the setup a little, the track worked. They want to leave it up for Grandpa Cochran to see, but I'm not sure that I can put up with it for another week. We will see.
