A lot less forgettable if you put the long end out but likely to get sued by whoever trips over it.
Not the perfect idea, but if you are on a 6,000+ mile road trip(more on that later) and it adds another layer of protection and becomes part of the usual, "Did we leave any thing behind in the room?" and undoing the other layers of protection pre-driving check list.
