Magnet roller the parking lot

Sharp metal debris can accumulate in our parking lot - this poses a hazard to car tires, so it's important to periodically pick up metallic sharp objects using our magnet roller.

1. Retrieve the magnet roller, usually located near the recycling bin by the forge area. 
2. Walk the roller all throughout the parking lot as if you were vacuuming a floor.
3. Bring the roller into the forge, turn off the magnet so stuff falls off, and shop vac up any recovered debris
