If your driveway is anything like mine, it is a veritable moss factory. Before all that beautiful moss gets covered by snow, destroyed by snow plows, or killed by salt, scrape it up now with that snow shovel you have handy. It can be used as grass in a mini setting or in terrariums. Keep it slightly damp with some light and it should last a long time. I am going to wrap some of mine around lava rocks to make moss boulders.
