Covert ventilation at night.

I'll try to reword that a bit... expecting of course a few about what a lot of hot air this is!

To remove hot air, blowing or helping it out is usually more effective than blowing cool air in... provided vents for incoming air are provided where it's cool(er).

When air is speeded up it cools down a bit and also has a wind-chill factor, increasing the effect...

I was sort of trying to point out the problem a lot of buildings (and maybe vehicles) have of forcing cool air in without helping the hot air out...

We like those spuds too Ken, onto the 3rd row now

Yes I also have trouble with pedants. It is not as though anyone couldn't see what it was you were getting at was it.
Anyway I drilled a matrix of holes in the table leg and sure enough a cool draft circulates around ones nether regions when for instance seated for a meal. I admit that the effect is largely psychological but then so are so many things believed by otherwise logical people.

(Yes those spuds have set us thinking)

I would think that if you plan to stay in autoroute stops quite regularly then its worth installing a "narcotics alarm"

Well, some of us will have the alarm going off regular then

Yeah, but you guys would only have false alarms.
