Oh the noise, take some very loud fireworks, The Dutch will it can be like WW3 kicking off at times, the cars pass so often that you get used to them.
I have started taking some fruit etc as well, on the circuit you can eat lots of meat & chips but after a while the desire for fruit & veg grows.
We also head off to a decent hotel on the way back (Sunday Night), a shower in clean surroundings is always nice
