I dont understand why a licence for 15,000 people is required if events are rarely going to go above 10,000. The over crowding at the jerk cookout over the period of years it was staged was bad enough, even before it reached the 20,000 number! The museum cannot cater for parking, so where are the 15,000 people (or even 10,000) going to park? And while I understand the Museum gets it's funding through such events, the idea of this number of people streaming out of the park at 11.30pm intoxicated in some cases, horrifies me. Before anyone justifies numbers by using the the carol concert as an example, this is a family event that doesnt encourage boozing and finishes at a reasonable hour ONCE A YEAR.
