Gloves in so I can turn 'em inside out to thaw on a radiator. Boots on a radiator if they're wet. Update what I've cleaned on the computer, update who has sent cheques/paid by bank transfer.
Make sure the flasks are taken from the van and washed.
Make any calls/texts that are required.
And if it looks like it's going to freeze,
1. Run an extention cable upto the van and set the timer for the imersion heater to click on at 4.00 am.
2. Take in poles and hose reels.
3. Disconnect pumps and take 'em in (very easy to do since I've made it that way).
But I didn't do that last night!
