Through the very murky screen on this car park ticket machine you can see it says 'Not in use' and there isn't another one. I rang the number and they took my details saying it's fine to park for free. It's these little things that brighten up the day.

This car park is always nearly empty which surprises me as you can get two hours for free and it's only five minutes walk into Warwick centre. I'm not saying where though else you'll all start using it!
