Fluent NHibernate - recursive maps

Question

I have an object that represents a Location. Locations can contain other locations. How can I represent this relationship with Fluent NHibernate. The class looks like this:

public class Location : EntityBase
{
    #region Properties
    public string LocationName { get; set; }
    public Location ParentLocation { get; private set; }

    private List<Location> _locations = new List<Location>();
    public IEnumerable<Location> Locations
    {
        get { return _locations; }
    }

    private List<Device> _devices = new List<Device>();
    public IEnumerable<Device> Devices
    {
        get { return _devices; }
    }

    #endregion
    //Other logic omitted
}

Thanks.
