Don't tend to write down session plans. 
BUT. 
When you're doing an assessment that was confirmed as a 'go' less than 48 hours ago.
(but you've been waiting for the right conditions since Feb).
And you're really tired. 
And a bit life stressed.
And the environment is very definitely going to tick the Advanced box.
And 2 of 3 of your group are new to you.

A bit of a scribble is probably a good idea! 

Job done.
