NaNoWriMo Strategies

#NaNoWriMo is becoming dangerously close. I am still researching the landscape of the Scottish Highlands in pre-Roman Britain. I need to know the type of tree the hero is going to see a red squirrel in or the cry of the red kite that the hero needs to recognise. Experience tells me that these issues will stop me dead and I can't afford to even pause in the mad writing sprint coming up. There's also a limit to how many times you can use xxxx before you go mad.
