The old machine shop had been vacated a few months ago, a more modern replacement having been built about a block up the road. And when the university's maintenance department gave up their claim to the building, the science department swooped in and planted their flag. Having their experiment labs was nice, but they were too small. This allowed the department to work on larger-scale experiments. Fortunately, the robotics group had finished up their work in the shop on Friday afternoon, leaving the floor cleared and the weekend open for more unofficial activities.
