Check with the fishery.
If the weather is dry enough, maybe no need for a tent for an overnight session, so nobody is any the worse off.
As @newmarket puts it, I'm a lunatic, but sleeping under the stars is fine.
In terms of the tents, olive green is more country coloured over the blue. Come to that though, ridge tents or dome style?
That in itself is a fun one as if you have a low green dome tent you could 'get away with it'.
