With Thanksgiving in the books, many are turning their attention to the December holiday season.  For many, that means getting a Christmas tree.  Bethel Fire & EMS are again holding a tree sale as a fundraiser for the department.  They're also offering a safety reminder for people who do get live trees.  Whether it's a pre-cut tree from the firehouse, or somewhere else, or picked fresh from a farm, Bethel firefighters say it’s important to cut a slice off the bottom of the tree to ensure it will take water once home in the stand.  Even if you cut down a tree freshly, you’ll want to make sure the base is fresh because a properly hydrated tree lessens the risk of fire.  Bethel Fire officials say a dry Christmas tree burns with more energy/intensity than a gallon of gasoline.
