Hi B.C.C.L,
Two years ago I took the family on a roadtrip and one of the activities was going to a traditional drive-in movie, the same kind I used to go to as a kid 40 years ago. I saw people in other cars taping mesh screening over their side window openings and thought it odd?
All went well in our mini-van and we sat with the windows down until dusk, then the mosquitos came out in hoards so we quickly rolled-up the windows, but with 5 of us in the van this caused the windshield to fog-up! The theatre had a rule against idling of vehicles so I had a problem with 3 upset children (and DW but we will not talk about that).
So I dug into the car/camping kit and found some PIC coils to burn. They cannot be good for you and it smelled up the van but we did finally get to see the movie.
So I agree with you, I think some mesh screen in a car kit is a great idea.
Mike
