I know it is obvious, but I have been imagining sitting outside, cooking on the stove/bbq, even campsite 'facilities' and the eventuality of rain. I have thought about bedding and going to bed, but the actually sleeping part has suddenly dawned on me!
I'm not sure I will be able to switch off enough to sleep.
Also, what if the weather is like this? There is no way I will be able to sleep in a tent throughout gales and heavy downpour!
I am a twat aren't I? :o
