I get the impression from a number of expert posters that the Cirrus is not a very good glider. (and my long ago experience with a Franklin engine has given me a strong preference for Lycoming!)
If all you power pilots simply shut down your engines and seriously took up gliding you would be much much safer! We seldom fly at night, in poor weather, or IMC.....though we do fly in interesting terraine.
And there is no pressure involved in persuading a reluctant family to come along for the ride...most cross country pilots fly alone!
