Might come in handy.

Have you got anything useless in your van which you think you might need one day so you take it with you on every trip and never use. We have, I shamefully have to admit an umbrella type fly cover, to keep the insects off food. more the sort of thing you'd put over the cucumber sandwiches!? Still at least it's lightweight and is hidden from view, maybe it will keep the flies off  barbecue food one day but it's still NEVER been used.....
