I go every year and have never had a problem - I think it is an amazing day.
I have always left late afternoon, however, and I tend to like slightly wussy things like tea dance tents.

The park is zoned and I think there must be a fighting zone somewhere but I have never seen it. There are some beautiful police horses outside.

I think they let all the criminals out of the cells of lewisham police station last night so they would have enough staff free to police it today
