I agree about leaving rubbish around, we put rubbish in bins the following morning and recycle what we can, if facilities are there. Some people take this further, when away at the weekend we had just settled to sleep around 11ish, someone started putting bottles into recycling bins, all you could hear was the smashing of bottles, they had obviously had a good night, I'm sure it could have waited til the morning though.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
